Genna purchased a pair of shoes on a web site.The original price of the shoes was $120. She used the coupon code to receive a 20% discount. The web applied a 15% service fee to the discounted price. Genna's shoes were less than the original price by what percent

$116

Step-by-step explanation:

the total discount is 20-15 = 5%

the dicount = (5*120)/100 = $4

So she bought it with price = 120 - 4 = $116

8%

Step-by-step explanation:

1. Apply the discount to the original price

20% of 120 (0.2*120) is 24, thus Genna saves 24 dollars

120-24 = 96 (the new price of the shoes, with the coupon applied)

2. Apply the service fee to the discounted price

15% of 96 (0.15*96) = 14.4

This number is the amount of money being added to the discounted price, as it is an additional fee

96 + 14.4 = 110.4

3. Find the percent discount Genna's shoes are using the new price.

1 - (New price/Old price) = Percent discount

110.4/120 = 0.92

1 - 0.92 = 0.08

The shoes are 92% of the original price. Thus, the shoes are 8% less than the original price.
