David and Gabriel had $192 and $156 respectively. Each of them bought a blouse and a hoodie at the same price. The cost of the blouse was 5 times as much as the hoodie. In the end, David had 4 times as much money as Gabriel. What was the difference between the cost of the hoodie and the blouse?

	David	Gabriel	Difference
Before	$192	$156	$36
Change	- 6 p	- 6 p
After	4 u	1 u	3 u

Since David 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.

4 u - 1 u = 192 - 156
3 u = 36

1 u = 36 ÷ 3 = 12

Cost of 1 blouse = 5 p
Cost of 1 hoodie = 1 p

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

6 p = 156 - 12
6 p = 144

1 p = 144 ÷ 6 = 24

Difference in the cost between the blouse and the hoodie
= 5 p - 1 p
= 4 p
= 4 x 24
= $96

Answer(s): $96
