Question

Ozzie has a coupon for 5% off any purchase in his favorite bakery. When Ozzie stops to buy some cookies, he discovers that all cookies are on sale for 15% off the regular price. The cookies are regularly $5.89 per dozen. If Ozzie uses his coupon and pays 7% sales tax, how much does he pay for two dozen cookies?
a.
$9.42
b.
$9.51
c.
$10.08
d.
$10.18

Answer 1

Regular price for two dozen = 2 × $5.89 = $11.78.
With 15% and 5% off: multiply by 0.85 × 0.95 = 0.8075 → discounted price = 11.78 × 0.8075 = $9.51235.
Add 7% tax: 9.51235 × 1.07 = $10.1782 ≈ $10.18.

Answer: d. $10.18
