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?
he should have calculated
15 − (9 + 2.65 + 1.35 + 2(1.74))
that is, add up all the expenses and subtract the total from 15
15 - 9 - 2.65 - 1.35 - 2(1.74) = ?

To find out why George does not have enough money, let's evaluate the numerical expression he used:
15 - 9 + 2.65 + 1.35 + 2(1.74)
First, we'll perform the multiplication operation by multiplying 2 with 1.74:
2(1.74) = 3.48
Now, let's substitute the result back into the expression:
15 - 9 + 2.65 + 1.35 + 3.48
Adding up the values, we get:
6 + 2.65 + 1.35 + 3.48 = 13.48
So, the result of the numerical expression is 13.48.
Since George has only $15, which is greater than 13.48, he should have enough money to buy the items. However, if George does not have enough money, it's possible that there are additional expenses or the prices of the items have changed since he calculated the expression.
