Question

Martinez purchased a pair of shoes on a web site. the original price of the shoes was $75. she used a coupon code to recive 20% discount ? the web site applied a 10% service fee to the discounted price . Martinez shoes were less than the original price by what percent​

Answer 1

$9 or 9% less

Explanation:

Original Price = OP

$75= OP

75 x .2 (20% discount) = 15

$15 discount

$75 - $15 = $60

$60 x .1 (service fee) = 6

$60 + $6= $66

Op ($75) - $66 = 9

$9 less than OP

How I check the percentage (probaly not how ur supposed to but ah well)

75 = 100%

75 + 25 = 100 but 25 more than 100%

66 + 25 = 91, also makes 75 100% again

100%-91%=9%
