Answer: Jeanettes ticket was less than the original price by 28%
Explanation:
The original price of the ticket was $75. She used a coupon code to receive a 20% discount. This means that the amount of discount that she got is
20/100 × 75 = 15
The discounted price would be
75 - 15 = $60
The website apply to 10% service fee to the discounted price. This means that the amount of service fee charged by the website is
10/100 × 60 = $6
The final cost of the ticket is
60 - 6 = $54
The difference between the final price and the original price is
75 - 54 = 21
The percentage difference in the prices would be
21/75 × 100 = 28%
