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:

Question

15 − 9 + 2.65 + 1.35 + 2(1.74)

Can you help him determine why he does not have enough money?

that is, add up all the expenses and subtract the total from 15

Answer 2
