Cole and Simon had $126 and $81 respectively. Each of them bought a skirt and a jacket at the same price. The cost of the skirt was 5 times as much as the jacket. In the end, Cole had 4 times as much money as Simon. What was the difference between the cost of the jacket and the skirt?

	Cole	Simon	Difference
Before	$126	$81	$45
Change	- 6 p	- 6 p
After	4 u	1 u	3 u

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

4 u - 1 u = 126 - 81
3 u = 45

1 u = 45 ÷ 3 = 15

Cost of 1 skirt = 5 p
Cost of 1 jacket = 1 p

Total cost of 1 skirt and 1 jacket
= 5 p + 1 p
= 6 p

6 p = 81 - 15
6 p = 66

1 p = 66 ÷ 6 = 11

Difference in the cost between the skirt and the jacket
= 5 p - 1 p
= 4 p
= 4 x 11
= $44

Answer(s): $44
