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

STEP 1:
Find discounted price.
Discounted $= original $ - (original $ * % discount)

Discounted $= $75 - ($75 * 20%)
Discounted $= 75 - 15
Discounted $= $60

STEP 2:
Find discounted $ plus service fee.
Price plus fee= discounted $ + (discounted $ * service fee %)

Price plus fee= $60 + ($60 * 10%)
Price plus fee= 60 + 6
Price plus fee= $66

STEP 3:
Find % change.
% change formula= (new # - original #) ÷ original # x 100

% change= (66-75)÷ 75 x 100
% change= -9 ÷ 75 x 100
% change= -0.12 x 100
% change= -12%

***the negative indicates a decrease

ANSWER: Her ticket was less than the original by 12%.

Hope this helps! :)
