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.
a.
paid $5.63 too little
b.

c.
paid the correct amount
d.

Answer 1

First find the pre-discount total:
32.65 + 3(14.89) + 39.99 = 32.65 + 44.67 + 39.99 = 117.31

Apply 10% discount: 117.31 × 0.90 = 105.579 (rounded to cents gives 105.58)

Apply 8% tax: 105.579 × 0.08 ≈ 8.446 (rounded to cents gives 8.45)

Total ≈ 105.58 + 8.45 = 114.03

So Manny paid the correct amount. Answer: c.
