Cody and Howard had $140 and $108 respectively. Each of them bought a sweater and a skirt at the same price. The cost of the sweater was 4 times as much as the skirt. In the end, Cody had 5 times as much money as Howard. What was the difference between the cost of the skirt and the sweater?

	Cody	Howard	Difference
Before	$140	$108	$32
Change	- 5 p	- 5 p
After	5 u	1 u	4 u

Since Cody and Howard 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 = 140 - 108
4 u = 32

1 u = 32 ÷ 4 = 8

Cost of 1 sweater = 4 p
Cost of 1 skirt = 1 p

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

5 p = 108 - 8
5 p = 100

1 p = 100 ÷ 5 = 20

Difference in the cost between the sweater and the skirt
= 4 p - 1 p
= 3 p
= 3 x 20
= $60

Answer(s): $60
