Brandon, Carl and Eric shared a sum of money. The amount received by Carl was ²₃ the amount of money received by Eric. After Brandon had given $53 to Carl and $28 to Eric, Carl gave $4 to Eric. In the end, 3 of them had the same amount of money. Find the difference between the amount of money that Brandon and Carl had at first.

	Brandon	Carl	Eric
Before	2 u + 130	2 u	3 u
Change 1	- 53	+ 53
Change 2	- 28		+ 28
Change 3		- 4	+ 4
After	2 u + 49	2 u + 49	3 u + 32

Amount that Carl had in the end = 2 u + 49 

Amount that Eric had in the end = 3 u + 32

Amount that Brandon had at first 
= 2 u + 49 + 53 + 28
= 2 u + 130

Amount that Carl and Eric had in the end is the same.

2 u + 49 = 3 u + 32
3 u - 2 u = 49 - 32

1 u = 17

Amount that Brandon and Carl had in the end is the same.

Amount that Brandon had in the end
= 2 u + 49
= 2 x 17 + 49
= 34 + 49
= $83

Amount that Brandon had at first
= 83 + 53 + 28
= $164

Difference in the amounts between Brandon and Carl at first
= 164 - 34
= $130

Answer(s): $130
