Jeanette purchased a concert ticket on a web site. the original price of the ticket was $75. she used a coupon code to receive a 20% discount. the web site applied a 10% service fee to the discounted price. jeanette’s ticket was less than the original price by what percent?

Jeanette’s ticket was less than the original price by 12 percent

Step-by-step explanation:

1. Let's calculate the 20% discount price Jeanette received:

75 - 0.2 * 75 = 75 - 15 = $ 60

The discounted price is $ 60

2. Let's calculate the 10% service fee to the discounted price:

60 + 0.1 * 60 = 60 + 6 = $ 66

The price including the service fee is $ 66

3. Finally, let's calculate the less percentage than the original price:

Let's use the Direct Rule of Three, this way:

Price     Percentage

75              100

66                x

75x = 66 * 100

75x = 6,600

x = 6,600/75

x = 88

Less percentage = 100 - 88 = 12%

Jeanette’s ticket was less than the original price by 12 percent
