Problema Solution

the star wars episode cd is on sale for $18 If this represents an 18% discount rate, what was the original price of the cd?

Answer provided by our tutors

Sales price after discount = $18

Discount rate = 18%

 

Let original price = $ x

Price after discount = x - 18% of x = x - 0.18x = 0.82x

=> 18 = 0.82x

=> x = $21.95
