Cody and Gabriel had $153 and $135 respectively. Each of them bought a jacket and a blouse at the same price. The cost of the jacket was 5 times as much as the blouse. In the end, Cody had 3 times as much money as Gabriel. What was the difference between the cost of the blouse and the jacket?

	Cody	Gabriel	Difference
Before	$153	$135	$18
Change	- 6 p	- 6 p
After	3 u	1 u	2 u

Since Cody and Gabriel 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 - 135
2 u = 18

1 u = 18 ÷ 2 = 9

Cost of 1 jacket = 5 p
Cost of 1 blouse = 1 p

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

6 p = 135 - 9
6 p = 126

1 p = 126 ÷ 6 = 21

Difference in the cost between the jacket and the blouse
= 5 p - 1 p
= 4 p
= 4 x 21
= $84

Answer(s): $84
