Answer:
Step-by-step explanation:
The original price of the shoes was $75.
She used a coupon code to receive a 20% discount. The value of the discount would be
20/100 × 75 = 0.2 × 75 = 15
The discounted price of the shoe with the applied coupon would be
75 - 15 = $60
The website applied a 10% service fee to the discounted price. The value of the service charge on the discounted price would be
10/100 × 60 = 0.1 × 60 = 6
The final price of the shoe would be
60 + 6 = $66
The difference between the price paid by martinez and the original price is 75 - 66 = 9
The percentage by which it was lesser than the original price would be
9/75 × 100 = 12%
