Question

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?

Answer 1

10%

Explanation:

20%-10%= 10%

Answer 2

The problem says that the original price of the ticket was $75 and Jeanette used a coupon code to receive a 20% discount. So, you have:

20%=20/100=0.20
75$x.0.20=15$

The price when she received a 20% discount was:

75$-15$=60$

Then, the web site applied a 10% service fee to the discounted price, so you have:

10/100=0.10
75$x0.10=7.5$
60$+7.5$=67.5$

So, if 75$ is the 100% of the price, what percentage represents 67.5$?

75$--------100%
67.5$------x

x=67.5x100/75
x=90%

Then, you obtain:

100%-90%=10%

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

The answer is: 10%
