Tim and John had $195 and $139 respectively. Each of them bought a cardigan and a hoodie at the same price. The cost of the cardigan was 4 times as much as the hoodie. In the end, Tim had 5 times as much money as John. What was the difference between the cost of the hoodie and the cardigan?

	Tim	John	Difference
Before	$195	$139	$56
Change	- 5 p	- 5 p
After	5 u	1 u	4 u

Since Tim and John bought the same items at the same price, the difference in the amounts they had remains unchanged at first and in the end.

5 u - 1 u = 195 - 139
4 u = 56

1 u = 56 ÷ 4 = 14

Cost of 1 cardigan = 4 p
Cost of 1 hoodie = 1 p

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

5 p = 139 - 14
5 p = 125

1 p = 125 ÷ 5 = 25

Difference in the cost between the cardigan and the hoodie
= 4 p - 1 p
= 3 p
= 3 x 25
= $75

Answer(s): $75
