Question

The original price of a gold ring is $40. Which coupon is a better deal? $15 off any ring or30% off any purchase

Answer 1

$15 off any ring

Explanation:

The original price of the gold ring = $40.

Coupon 1: $15 off any ring

`\text{Sales Price}=40-15=\$25`

Coupon 2: 30% off any purchase ​

`\begin{gathered} \text{ Sales Price}=40-(30\%\text{ of 40\rparen} \\ =40-(0.3*40) \\ =40-12 \\ =\$28 \end{gathered}`

We see that the sales price for Coupon 1 is lower, therefore, the coupon "$15 off any ring " gives a better deal.
