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. HO 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
To calculate how much Ozzie pays for two dozen cookies, first calculate the price of one dozen cookies after the 15% discount:
$5.89 * 0.15 = $0.8835
$5.89 - $0.8835 = $5.0065
Now apply the 5% coupon to this price:
$5.0065 * 0.05 = $0.2503
$5.0065 - $0.2503 = $4.7562
Now multiply this price by 2 to account for two dozen cookies:
$4.7562 * 2 = $9.5124
Finally, add the 7% sales tax:
$9.5124 * 0.07 = $0.6669
Total cost for two dozen cookies = $9.5124 + $0.6669 = $10.1793
Rounded to two decimal places, Ozzie pays $10.18 for two dozen cookies, which is option d. $10.18.
