Manny makes the following purchases at the store:

pair of jeans for $32.65

3 t-shirts for $14.89 each

pair of sneakers for $39.99

the store is having a promotional sale where 10% is taken off of each customer’s total purchase before tax. the sales tax is 8%. if manny paid $114.03 , then he for his purchase.

The correct answer is:

He paid the correct amount.

Explanation:

First we find the subtotal of Manny's items:

32.65+3(14.89)+39.99 = 32.65+44.67+39.99 = 117.31

Next, we calculate the discount. If he gets 10% off, this means he pays 100%-10% = 90% of the total. 90% = 90/100 = 0.9:

0.9(117.31) = 105.579

Next we calculate the tax. Since tax is 8%, this means he pays 100% of his subtotal after discount plus the 8% tax; 100%+8% = 108%; 108% = 108/100 = 1.08:

1.08(105.579) = 114.02532 ≈ 114.03

Since this is what he paid, he paid the correct amount.

i believe the answer is d.
