before using his coupon, jule owed $86 for a pair of jeans. after he used the coupon, he owed $60.20. what percent discount did jule receive?
The price before the coupon is $86. After the coupon, the price is $60.20
We use subtraction to find the amount the coupon saved. The difference between 86 and 60.20 is:
86 - 60.20 = 25.80
The coupon saved $25.80. To find out what percentage savings this is, divide it by the original price and multiply by 100%:
25.80/86 x 100% = 30%
So the coupon must have been an 30% off coupon.
