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 him determine why he does not have enough money?
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.
