Bryan and Vaidev had $219 and $193 respectively. Each of them bought a shirt and a skirt at the same price. The cost of the shirt was 5 times as much as the skirt. In the end, Bryan had 3 times as much money as Vaidev. What was the difference between the cost of the skirt and the shirt?

	Bryan	Vaidev	Difference
Before	$219	$193	$26
Change	- 6 p	- 6 p
After	3 u	1 u	2 u

Since Bryan and Vaidev 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 = 219 - 193
2 u = 26

1 u = 26 ÷ 2 = 13

Cost of 1 shirt = 5 p
Cost of 1 skirt = 1 p

Total cost of 1 shirt and 1 skirt
= 5 p + 1 p
= 6 p

6 p = 193 - 13
6 p = 180

1 p = 180 ÷ 6 = 30

Difference in the cost between the shirt and the skirt
= 5 p - 1 p
= 4 p
= 4 x 30
= $120

Answer(s): $120
