Fabian and Pierre had $146 and $106 respectively. Each of them bought a jacket and a skirt at the same price. The cost of the jacket was 3 times as much as the skirt. In the end, Fabian had 5 times as much money as Pierre. What was the difference between the cost of the skirt and the jacket?

	Fabian	Pierre	Difference
Before	$146	$106	$40
Change	- 4 p	- 4 p
After	5 u	1 u	4 u

Since Fabian and Pierre 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 = 146 - 106
4 u = 40

1 u = 40 ÷ 4 = 10

Cost of 1 jacket = 3 p
Cost of 1 skirt = 1 p

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

4 p = 106 - 10
4 p = 96

1 p = 96 ÷ 4 = 24

Difference in the cost between the jacket and the skirt
= 3 p - 1 p
= 2 p
= 2 x 24
= $48

Answer(s): $48
