Zeph and Jeremy had $134 and $108 respectively. Each of them bought a blouse and a hoodie at the same price. The cost of the blouse was 4 times as much as the hoodie. In the end, Zeph had 3 times as much money as Jeremy. What was the difference between the cost of the hoodie and the blouse?

	Zeph	Jeremy	Difference
Before	$134	$108	$26
Change	- 5 p	- 5 p
After	3 u	1 u	2 u

Since Zeph and Jeremy 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 = 134 - 108
2 u = 26

1 u = 26 ÷ 2 = 13

Cost of 1 blouse = 4 p
Cost of 1 hoodie = 1 p

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

5 p = 108 - 13
5 p = 95

1 p = 95 ÷ 5 = 19

Difference in the cost between the blouse and the hoodie
= 4 p - 1 p
= 3 p
= 3 x 19
= $57

Answer(s): $57
