Jenson and Justin had $153 and $121 respectively. Each of them bought a skirt and a hoodie at the same price. The cost of the skirt was 4 times as much as the hoodie. In the end, Jenson had 3 times as much money as Justin. What was the difference between the cost of the hoodie and the skirt?

	Jenson	Justin	Difference
Before	$153	$121	$32
Change	- 5 p	- 5 p
After	3 u	1 u	2 u

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

3 u - 1 u = 153 - 121
2 u = 32

1 u = 32 ÷ 2 = 16

Cost of 1 skirt = 4 p
Cost of 1 hoodie = 1 p

Total cost of 1 skirt and 1 hoodie
= 4 p + 1 p
= 5 p

5 p = 121 - 16
5 p = 105

1 p = 105 ÷ 5 = 21

Difference in the cost between the skirt and the hoodie
= 4 p - 1 p
= 3 p
= 3 x 21
= $63

Answer(s): $63
