Question

Mary would like to buy a laptop computer with an original price of $964.60. Which coupon should she use? 50 % off or save $400.00

Answer 1

She should use 50% off.

964 divided by 1/2 = $482

964 - 400 = $564

Answer 2

We will do better using the 50% off

Explanation:

First find the price with the coupon

964.64 -400 = 564.60

Now find the price with 50% off

50% off means that we will pay 100-50 = 50 percent

964.60*50% =

964.60*.50

482.30

We will do better using the 50% off
