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

D  

Step-by-step explanation:  

you need to first do 5.89- [(5.89 * 15)/100]=5.89-0.8835=5.0065  

then 5.0065 * 2 = 10.013 because it is 15% each dozen then  

[(10.013 * 5)/100] =0.50065 then 10.013 - 0.50065 = 9.51235

and lastly (9.51235 * 7)/100 = 0.6658645  

finally 9.51235 + 0.6658645= 10.1782145

and then you just need to round it to the nearest hundredths and you will get 10.18

answer: 2/4
