Sally is buying new school supplies she uses a 15% off coupon on the set of markers that was originally $3 she also bought some papers that was 20% off total sally spent $5.35 after using her coupon how much was the original price of the paper

Okay

Let us find the amount of money used with the 15% off coupon
15 is 10 + 5
So we need to find 10 percent and 5 percent, add them, and take them away from 3.00
3.00 divided by 10 equals .30
.30 = 10%
5 is half of ten.
.30 divided by 2 is .15
.15=5%
.15 plus .30 equals 45
$.45 = 15%
$3.00 - $0.45 = $2.55 was how much she spent on the markers

Now keep in mind, that was the only coupon she used and the store had the paper 20% off. The total money she used, for the paper and markers, was $5.35. 5.35 - 2.55 = $2.80, the amount she used for the paper 20% off

To find how much it was, do 2.80 x 5 , since 20% x 5 equals 100%, a whole
2.80 x 5 = $14.00

The answer is that $14.00 was the original amount of the paper

But next time, please be clear :)
