In April​ 2008, an audio CD was available for ​$12.18. The list price​ (full price) of this CD was ​$16.92. What was the percent​ discount?

Answer 1

16.92 - 12.18 = 4.74

4.74/16.92 = ever so slightly more than 28% discount

.28(16.92) = $4.74 when rounded to nearest cent

get a 28% discount you pay 1-28 = 72% of the original price

.72(16.92) = about $12.18
