Question

A shopkeeper wants to sell a shirt originally priced at $120. Which deal will result in the greatest sale price of the shirt?A. 20% offB. $30 couponC. 15% off and then a $15 rebateD. 10% off and then a $20 rebate

Answer 1

Let's determine which sale is better.

20% means that the shirt will cost:

`120(0.8)=96`

$30 coupon means that the shirt will cost $90

15% off and $15 rebate means:

`120(0.85)-15=87`

10% off and $20 rebate means:

`120(0.9)-20=88`

Comparing the prices we conclude that the best deal is C
