Question

You can save $45 at Kohl's if you use a coupon for 15% off. What would your total be before using the coupon?

Answer 1

$300

Explanation:

Since you save $45 by using a coupon for 15% off, that means that 15% of the original price is $45.

We can use a proportion.

15% is to 45 as 100% is to x.

15/45 = 100/x

1/3 = 100/x

1 × x = 3 × 100

x = 300

Answer: The total without the coupon is $300.

Answer 2

$300

Explanation:

15% / 3 = 5%

45 / 3 = $15

5% * 2 = 10%

15 * 2 = $30

10% * 10 = 100%

30 * 10 = $300

300 x 0.85 (-15%)

255

255 + 45 = 300
