Answer:
Step-by-step 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
