Question

help would be so appreciated :) All CD’s are on sale for 20% this week. The CD is $9.99. What is the original price of the CD? please explain steps!

Answer 1

$12.49

Explanation:

The price was originally x, then we took off 20% of x. The result was $9.99. Therefore:

x − 0.20 x = 9.99

0.80 x = 9.99

x = 12.4875

Rounding to the nearest cent, the original price was $12.49.
