1 pack of mechanical pencils for $3.68
2 packs of lead refills for $1.88 each
Leonardo has 2 coupons, each for 45 cents off on the purchase of a pack of lead refills. The coupons are applied after tax and the sales tax is 5% of the purchase. If Leonardo paid $30.89 , then he _____ for his purchase.
a.
did not pay enough
b.
paid the correct amount
c.
paid $0.04 too much
d.
paid $0.57 too much

Answer 1

Compute the subtotal:
16.89 + (5 × 1.19) + 3.68 + (2 × 1.88) = 16.89 + 5.95 + 3.68 + 3.76 = 30.28.

Sales tax (5%): 0.05 × 30.28 = 1.514 → $1.51 (rounded to cents).

Total after tax: 30.28 + 1.51 = 31.79.
Coupons: 2 × $0.45 = $0.90, applied after tax: 31.79 − 0.90 = 30.89.

He paid $30.89, so he paid the correct amount. Answer: b.
