Paul and Lee had $120 and $92 respectively. Each of them bought a jacket and a blouse at the same price. The cost of the jacket was 4 times as much as the blouse. In the end, Paul had 5 times as much money as Lee. What was the difference between the cost of the blouse and the jacket?

	Paul	Lee	Difference
Before	$120	$92	$28
Change	- 5 p	- 5 p
After	5 u	1 u	4 u

Since Paul and Lee 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 = 120 - 92
4 u = 28

1 u = 28 ÷ 4 = 7

Cost of 1 jacket = 4 p
Cost of 1 blouse = 1 p

Total cost of 1 jacket and 1 blouse
= 4 p + 1 p
= 5 p

5 p = 92 - 7
5 p = 85

1 p = 85 ÷ 5 = 17

Difference in the cost between the jacket and the blouse
= 4 p - 1 p
= 3 p
= 3 x 17
= $51

Answer(s): $51
