Problem: A teacher initially had 'a' sheets of special star stickers in her drawer. She then used 60 stickers for rewarding her students in class, and now she has only 2 sheets left. How many sheets of star stickers did the teacher initially have in her drawer?
Llama 3 8B:
Reasoning: Let's say the number of sheets the teacher initially had is 'a'. After using 60 stickers, she has 2 sheets left. This means that the total number of stickers she had initially is equal to the number of stickers she used (60) plus the number of stickers in the 2 sheets she has left. Since each sheet has 25 stickers (assuming standard sticker sheets), the number of stickers in 2 sheets is 2 x 25 = 50. So, the total number of stickers the teacher had initially is 60 + 50 = 110. Since each sheet has 25 stickers, the number of sheets the teacher initially had is 110 / 25 = 4.4. Since you can't have a fraction of a sheet, the teacher initially had 4 sheets of star stickers. ### Answer: 4
