Question

Jacob found a computer game that was on sale at 20% off its original price. Which expression below will find the sale price, s, of the computer game, if p represents the original price of the product?

Answer 1

Explanation:

Let p represent the original price of the computer game.

Let s represent the sales price of the computer game.

Jacob found a computer game that was on sale at 20% off its original price. This means that the amount that was taken off the original price would be

20/100 × p = 0.2 × p = 0.2p

The expression for the sale price would be

s = p - 0.2p

s = 0.8p
