Question

You are buying six hats and have a coupon for 15 dollars off. You spend $45. How much is each hat?

Answer 1

$7.5¢ or
`7(1)/(2)`

Explanation:

Do not use This solution:

Firstly, lets find how much the hats cost initially before the 15% coupon. To do that, divide, not multiply, divide $45 by 15% because 15% off means multiply 15% from the original price. But in this case we need to find the initial amount before the 15% coupon.

15% =
`(15)/(100)`

Now, set it up;

`(15)/(100)` ×
`(45)/(1)`

Correct solution!

45 ÷ 6 = 7.5

Answer 2

$10

Explanation:

6x-15=45

+15. +15

6x=60
