Vaidev and Elijah had $204 and $177 respectively. Each of them bought a hoodie and a blouse at the same price. The cost of the hoodie was 5 times as much as the blouse. In the end, Vaidev had 4 times as much money as Elijah. What was the difference between the cost of the blouse and the hoodie?

	Vaidev	Elijah	Difference
Before	$204	$177	$27
Change	- 6 p	- 6 p
After	4 u	1 u	3 u

Since Vaidev and Elijah 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 = 204 - 177
3 u = 27

1 u = 27 ÷ 3 = 9

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

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

6 p = 177 - 9
6 p = 168

1 p = 168 ÷ 6 = 28

Difference in the cost between the hoodie and the blouse
= 5 p - 1 p
= 4 p
= 4 x 28
= $112

Answer(s): $112
