Henry and Rael had $132 and $68 respectively. Each of them bought a sweater and a skirt at the same price. The cost of the sweater was 3 times as much as the skirt. In the end, Henry had 5 times as much money as Rael. What was the difference between the cost of the skirt and the sweater?

	Henry	Rael	Difference
Before	$132	$68	$64
Change	- 4 p	- 4 p
After	5 u	1 u	4 u

Since Henry and Rael bought the same items at the same price, the difference in the amounts they had remains unchanged at first and in the end.

5 u - 1 u = 132 - 68
4 u = 64

1 u = 64 ÷ 4 = 16

Cost of 1 sweater = 3 p
Cost of 1 skirt = 1 p

Total cost of 1 sweater and 1 skirt
= 3 p + 1 p
= 4 p

4 p = 68 - 16
4 p = 52

1 p = 52 ÷ 4 = 13

Difference in the cost between the sweater and the skirt
= 3 p - 1 p
= 2 p
= 2 x 13
= $26

Answer(s): $26
