Problem: Tom has a total of 10 cucumbers. He initially had 1 cucumber. How many more cucumbers did he add to his collection?

CodeLlama 34B:

  Let's use a number line to represent the cucumbers.

Initially, Tom had 1 cucumber, which we can represent as:

1

He added more cucumbers to his collection, so we can represent that as:

1 + x

Where x is the number of cucumbers he added.

We know that the total number of cucumbers Tom has is 10, so we can set up the equation:

1 + x = 10

To solve for x, we can subtract 1 from both sides:

x = 10 - 1

x = 9

So, Tom added 9 more cucumbers to his collection.

### Answer: 9

Problem: Julia has 10 dollars in her wallet. If she originally had 1 dollar before her mother gave her some more money, how much money did her mother give her?

CodeLlama 34B:

  Let's call the amount of money Julia's mother gave her "x".

We know that Julia originally had 1 dollar, so she had a total of 1 + x dollars after her mother gave her more money.

We also know that Julia has 10 dollars in her wallet now, so she has a total of 10 - x dollars.

Since Julia has a total of 10 - x dollars, we can set up the equation:

10 - x = 1 + x

Simplifying the equation:

10 = 2x

Dividing both sides by 2:

5 = x

So, Julia's mother gave her 5 dollars.

Expected answer: 9

Correct? No

Problem: During a table hockey game, Billy scored a total of 10 goals. If he scored 6 goals in the first half of the game, how many did he score in the second half?

CodeLlama 34B:

  To find out how many goals Billy scored in the second half of the game, we need to subtract the number of goals he scored in the first half from the total number of goals he scored.

Let's use a equation to represent this:

Total goals - First half goals = Second half goals

We know that the total number of goals Billy scored is 10, and he scored 6 goals in the first half. So, we can plug these values into the equation:

10 - 6 = Second half goals

To solve for the second half goals, we need to subtract 6 from 10:

10 - 6 = 4

Therefore, Billy scored 4 goals in the second half of the game.

Expected answer: 4

πŸ”— Problem

Problem: Sarah bought a total of 10 ice creams, and she bought 9 of them on her first shopping trip. How many ice creams did Sarah buy on her second shopping trip?

CodeLlama 34B:

  Let's start by using the information that Sarah bought 9 ice creams on her first shopping trip. We can write this as an equation:

9 + x = 10

where x is the number of ice creams Sarah bought on her second shopping trip.

To find the value of x, we can subtract 9 from both sides of the equation:

x = 10 - 9

x = 1

So, Sarah bought 1 ice cream on her second shopping trip.

Expected answer: 1

πŸ”— Problem

Problem: In a pizza party, Maria prepared a total of 10 pizzas. Out of these, 6 were pepperoni pizzas. How many were mushroom pizzas?

CodeLlama 34B:

  Let's use a Venn diagram to solve this problem.

Let A represent the set of all pizzas, and let B represent the set of pepperoni pizzas.

We know that 6 pizzas are pepperoni pizzas, so the size of set B is 6.

We also know that the total number of pizzas is 10, so the size of set A is 10.

Using the formula for the size of the union of two sets, we can calculate the size of the set of all pizzas that are not pepperoni:

|A \ B| = |A| - |B|
|A \ B| = 10 - 6
|A \ B| = 4

So, there are 4 mushroom pizzas.

Expected answer: 4

πŸ”— Problem

Problem: A computer costs 10 dollars. If you already paid 3 dollars, how much money do you still need to pay?

CodeLlama 34B:

  To find out how much money you still need to pay for the computer, you need to subtract the amount you have already paid from the total cost of the computer.

Total cost of computer = 10 dollars
Amount already paid = 3 dollars

Subtracting the amount already paid from the total cost gives you the amount still needed to be paid:

10 - 3 = 7 dollars

Therefore, you still need to pay 7 dollars for the computer.

We know that Peter had 10 shirts in his closet before buying a new shirt. So, the number of shirts he had before buying a new shirt is 10.

We also know that after buying a new shirt, Peter found out he only had one shirt before the purchase. So, the number of shirts he had before buying a new shirt is 1.

We can set up an equation to represent this information:

10 - x = 1

Where x is the number of shirts Peter bought.

Solving for x, we get:

x = 9

So, Peter bought 9 shirts.

Expected answer: 9

Problem: Grace enjoys strawberry picking and one day, she managed to get 10 strawberries. If she had already picked 2 strawberries prior to a particularly good area, how many strawberries did she pick from the good area?

CodeLlama 34B:

  Let's use a Venn diagram to represent the situation.

Let A represent the 2 strawberries that Grace picked prior to the good area, and let B represent the strawberries that Grace picked from the good area.

We know that the total number of strawberries that Grace picked is 10, so the union of A and B (A βˆͺ B) is equal to 10.

We also know that Grace picked 2 strawberries prior to the good area, so the size of set A (|A|) is equal to 2.

Using the formula for the union of two sets, we can write:

|A βˆͺ B| = |A| + |B|

Substituting the values we know, we get:

|A βˆͺ B| = |A| + |B|
10 = 2 + |B|
|B| = 8

Therefore, Grace picked 8 strawberries from the good area.

Expected answer: 8

πŸ”— Problem

Problem: Sam has 10 toy cars in total. If 7 of them are sports cars, how many of them are race cars?

CodeLlama 34B:

  Let's use a Venn diagram to represent the information given in the problem.

Let A represent the set of all toy cars, and let B represent the set of sports cars.

We know that 7 of the toy cars are sports cars, so the intersection of A and B has a size of 7.

We also know that 3 of the toy cars are race cars, so the intersection of A and C (where C represents the set of race cars) has a size of 3.

Using the Inclusion-Exclusion Principle, we can find the size of the union of A and B by subtracting the size of the intersection of A and B from the size of A, and then adding the size of the intersection of A and C:

|A βˆͺ B| = |A| - |A ∩ B| + |A ∩ C|
|A βˆͺ B| = 10 - 7 + 3
|A βˆͺ B| = 6

So, there are 6 toy cars that are either sports cars or race cars.

Expected answer: 3

  Let's start by using the information we know. Tom used 5 cans of green paint, so we can write:

5 + x = 10

where x is the number of cans of blue paint he used.

We can simplify the equation by subtracting 5 from both sides:

x = 10 - 5

x = 5

So, Tom used 5 cans of blue paint.

Problem: In the park, Mary saw 10 birds in total. She saw 3 sparrows. How many birds did she see other than sparrows?

CodeLlama 34B:

  Let's use a Venn diagram to represent the information given in the problem.

Let S be the set of all sparrows that Mary saw in the park.
Let B be the set of all birds that Mary saw in the park.

We know that |S| = 3, since Mary saw 3 sparrows.
We also know that |B| = 10, since Mary saw 10 birds in total.

Using the information-schema theorem, we can write:

|B| = |S| + |B ∩ S|

Substituting the values we know, we get:

10 = 3 + |B ∩ S|

Solving for |B ∩ S|, we get:

|B ∩ S| = 10 - 3 = 7

So, Mary saw 7 birds other than sparrows in the park.

Problem: John has a total of 10 chairs at home. If 7 of those are dining chairs, how many of the chairs are lounge chairs?

CodeLlama 34B:

  Let's use a Venn diagram to represent the information.

Let A represent the set of all chairs at home, and let B represent the set of dining chairs.

We know that 7 chairs are dining chairs, so the size of set B is 7.

We also know that the total number of chairs is 10, so the size of set A is 10.

Using the Venn diagram, we can represent the information as follows:

A = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10}
B = {1, 2, 3, 4, 5, 6, 7}

The size of the intersection of A and B is 7, which represents the number of chairs that are both dining chairs and lounge chairs.

To find the number of lounge chairs, we need to subtract the size of the intersection from the size of set A.

10 - 7 = 3

Therefore, there are 3 lounge chairs at home.

Problem: On a farm, there are 10 animals in total. Among them, 9 animals are chickens. How many animals are cows?

CodeLlama 34B:

  Let's use algebra to solve this problem. Let C represent the number of chickens and let C represent the number of cows.

We know that the total number of animals is 10, so we can write an equation based on that:

C + C = 10

We also know that 9 animals are chickens, so we can write an equation based on that:

C = 9

Now we can substitute the value of C into the first equation:

9 + C = 10

9 + 9 = 10

18 = 10

This equation is not true, so we have reached a contradiction. This means that our initial assumption that there are 9 chickens and 1 cow is incorrect.

Therefore, the answer is:

There are 0 cows.

Problem: Billy has 10 pens in total. If 7 of them are black, how many of them are blue?

CodeLlama 34B:

  Let's use a Venn diagram to represent the situation.

Let B represent the set of black pens and B represent the set of blue pens.

We know that 7 pens are black, so the size of the set B is 7.

We also know that the total number of pens is 10, so the size of the set P (which represents the set of all pens) is 10.

Using the formula for the size of a union of sets, we can write:

|P| = |B| + |B'|

where |B'| represents the size of the set of pens that are not black.

We know that |B| = 7, so we can substitute this value into the equation above:

|P| = |B| + |B'|
|P| = 7 + |B'|

We also know that |P| = 10, so we can substitute this value into the equation above:

10 = 7 + |B'|

Subtracting 7 from both sides of the equation, we get:

3 = |B'|

So, there are 3 blue pens.

Problem: Melanie has a total of 10 blankets. If 6 of them are woolen blankets, how many of them are cotton blankets?

CodeLlama 34B:

  Let's use a Venn diagram to represent the information given in the problem.

Let W be the set of all woolen blankets and C be the set of all cotton blankets.

We know that 6 blankets are woolen, so W = 6.

We also know that the total number of blankets is 10, so |C| = 10.

Using the Inclusion-Exclusion Principle, we can find the number of cotton blankets by subtracting the number of woolen blankets from the total number of blankets:

|C| = 10 - 6 = 4

Therefore, there are 4 cotton blankets.

Problem: On a farm, there are 10 cows in total. If 9 of these are brown, how many cows are black?

CodeLlama 34B:

  Let's use a Venn diagram to represent the information given in the problem.

Let B represent the set of brown cows and B' represent the set of black cows.

We know that 9 cows are brown, so |B| = 9.

We also know that the total number of cows is 10, so |B βˆͺ B'| = 10.

Using the Inclusion-Exclusion Principle, we can write:

|B βˆͺ B'| = |B| + |B'| - |B ∩ B'|

Substituting the values we know, we get:

10 = 9 + |B'| - |B ∩ B'|

Simplifying, we get:

|B'| = 10 - 9 - |B ∩ B'|

Since |B ∩ B'| ≀ min(|B|, |B'|), we know that |B ∩ B'| ≀ 1.

Therefore, |B'| = 10 - 9 - 1 = 1.

So, there is only 1 black cow.

Problem: John has a total of 10 toothbrushes. If he has 7 red ones, how many blue toothbrushes does he have?

CodeLlama 34B:

  Let's use a Venn diagram to solve this problem.

Let R represent the set of red toothbrushes and B represent the set of blue toothbrushes.

We know that John has 7 red toothbrushes, so the size of the set R is 7.

We also know that the total number of toothbrushes John has is 10, so the size of the set R βˆͺ B (the union of the sets R and B) is 10.

Using the Inclusion-Exclusion Principle, we can find the size of the set B by subtracting the size of the set R from the size of the set R βˆͺ B:

|B| = |R βˆͺ B| - |R|
|B| = 10 - 7
|B| = 3

Therefore, John has 3 blue toothbrushes.

Problem: In a homogeneous pillow shop, there are 10 blue and green pillows altogether. If there are 6 green pillows, how many blue pillows are there?

CodeLlama 34B:

  Let's use a Venn diagram to represent the information given in the problem.

Let B represent the set of blue pillows and G represent the set of green pillows.

We know that the union of B and G is the set of all pillows, which has 10 elements.

We also know that the intersection of B and G is empty, since the pillows are homogeneous.

Using the formula for the union of two sets, we can write:

|B βˆͺ G| = |B| + |G|

Substituting the given values, we get:

10 = |B| + 6

Subtracting 6 from both sides gives us:

4 = |B|

Therefore, there are 4 blue pillows in the shop.

Expected answer: 4

Correct? Yes

Problem: On a nearby planet, an alien discovered 10 new species of plants. If he found 7 of them during his morning walk, how many did he find during his evening walk?

CodeLlama 34B:

  Let's use "P" to represent the number of plants the alien found during his morning walk.

We know that the alien found 10 new species of plants in total, so the total number of plants he found is 10.

We also know that he found 7 plants during his morning walk, so we can write an equation:

P + 7 = 10

To solve for P, we can subtract 7 from both sides of the equation:

P = 10 - 7

P = 3

So, the alien found 3 plants during his evening walk.

Expected answer: 3

Problem: On Valentine's Day, John received 10 chocolates in total. He already had 4 chocolates before. How many chocolates was he given on Valentine's Day?

CodeLlama 34B:

  Let's use a system of linear equations to solve this problem.

Let x be the number of chocolates John was given on Valentine's Day.

We know that the total number of chocolates John received is 10.

So, we can write the first equation:

x + 4 = 10

We know that John already had 4 chocolates before Valentine's Day.

So, we can write the second equation:

x + 4 = 4

Now, we can solve the system of equations by subtracting the second equation from the first equation:

x + 4 - 4 = 10 - 4

This simplifies to:

x = 6

So, John was given 6 chocolates on Valentine's Day.

Expected answer: 6

Let C represent the set of unscented candles.

We know that A = B βˆͺ C, where B ∩ C = βˆ… (i.e., the sets of scented and unscented candles are mutually exclusive).

We also know that |B| = 8, so the number of scented candles is 8.

To find the number of unscented candles, we can use the equation |A| = |B| + |C|.

Substituting the values we know, we get:
