Question

Jeanette purchased a concert ticket on a website he original price of the ticket was $75 she used a coupon code to receive a 20% discount The website is applied a 10% service fee to the discounted price Jeanette's ticket was less than the original price by what percent?

Answer 1

If the original price is $75 and a 20% coupon was used then the price of the ticket is 80% of the original price and so:


`75 * 0.80 = 60`
Then a 10% service fee we have:


`60(1 + 0.10) = 60(1.10) = 66`
So the final price paid is $66. By what percent less we will use the percent difference formula:


`(75 - 66)/(75) * 100 = 12`
Therefore the price is 12% less than the original price of $75.
