Question

George has 15$. He tries to buy a movie ticket ($9.00), a pretzel ($2.65), a drink ($1.35), and two veggie cups ($1.74 each) but he does not have enough money . Look at the numerical expression George used: 15-9+2.65+1.35+2(1 .74). Can you help determine why he does not have enough money

Answer 1

George is adding instead of subtracting.

Answer 2

Sample Response: George did not put parentheses around the total snack amount to be subtracted from his $15. He needed to total the purchases and then subtract that amount from $15.
