Question

Students get a 15% discount off the original prices at the Everything Fluorescent store during its back to school sale. Find the amount of discount on fluorescent notebooks originally priced at $7.99.

Answer 1

The discount is $1.19 unless you have to round up than it is $1.20. in order to solve this problem you would set up a proportion. So your proportion would be x over 7.99 = 15 over 100. Than you would cross multiply. 7.99*15=119.85. and 100*x=100x. than u divided both sides by a 100. than x= 1.19. which 1.19 is the discount.
