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 him determine why he does not have enough money? 15 – 9 + 2.65 + 1.35 + 2(1.74) Use the order of operations to simplify this expression.

Answer:
George doesn’t have enough money because the total cost of what he wants to buy costs $16.48 and he has $15. This means he needs an extra $1.48 to be able to buy what he needs
Step-by-step explanation:
From the above 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 ($1.74 each) but he does not have enough money.
Look at the numerical expression George used: 15 −( 9 + 2.65 + 1.35 + 2(1.74) )
Use the order of operations to simplify this expression.
Using the order of operations we have:
=$ 15 – (9 + 2.65 + 1.35 + 2(1.74) )
= $15 -( 9 + 2.65 + 1.35 + 3.48 )
=$ 15 – (16.48)
= $-1.48
George doesn’t have enough money because the total cost of what he wants to buy costs $16.48 and he has $15. This means he needs an extra $1.48 to be able to buy what he needs
Answer:
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.
or
George tries to buy a movie ticket ($9.00), a pretzel($2.65), a drink ($1.35), and two veggie cups ($1.74 each)
9+2.65+1.35+1.74+1.74= 16.48
subtract 15 to 16.48
15-16.48= 1.48
he still needs $1.48
Step-by-step explanation:
they are both right 🙂
