An appliance store decreases the price of an 19-in. television set 15 % to a sale price of $ 551.23 . What was the original price?

Answer 1

Let x = original price

Sale Price = Original Price - Discount

551.23 = x - 0.15x Combine like terms

551.23 = 0.85x Divide both sides by 0.85

551.23/0.85 = 0.85x/0.85 Simplify

648.51 = x

The original price is $648.51
