We can use the percent formula to solve. The percent formula is below: ^part⁄_whole = ^%⁄₁₀₀ First, we have to determine the part. In this problem, the part is the $10 the customer saved using the coupon. We can find the original price by adding what the customer paid to what they saved with the coupon: $54.56 + $10 = $64.56 (the whole). So, the part of the percent formula is 10. The whole of the percent formula (the original price of the item) is $64.56. Now, we have to determine our percent. Since we we don't know the percent, this is where we are going to put our variable (x). ^part⁄_whole = ^%⁄₁₀₀ ¹⁰⁄_64.56 = ^x⁄₁₀₀ Cross multiply and solve for x: ¹⁰⁄_64.56 = ^x⁄₁₀₀ 64.56 • x = 10 • 100 64.56x = 1,000 64.56x ÷ 64.56 = 1,000 ÷ 64.56 x = 15.49 So, $10 is 15.49% of $64.56.
