Problem: In the same context as before, suppose instead of spending 59 dollars on a video game, Shay spent 86 dollars. Again, after his purchase, his friend borrows some money, giving back 13 dollars. Now, how much money does Shay have in total?

GPT-4o:

First, let's determine how much money Shay has after buying the video game. Shay starts with 93 dollars and spends 86 dollars on the video game:

\[ 93 - 86 = 7 \]
