Warren, Will and Tommy shared a sum of money. The amount received by Will was ⁴₅ the amount of money received by Tommy. After Warren had given $43 to Will and $28 to Tommy, Will gave $2 to Tommy. In the end, 3 of them had the same amount of money. Find the difference between the amount of money that Warren and Will had at first.

	Warren	Will	Tommy
Before	4 u + 112	4 u	5 u
Change 1	- 43	+ 43
Change 2	- 28		+ 28
Change 3		- 2	+ 2
After	4 u + 41	4 u + 41	5 u + 30

Amount that Will had in the end = 4 u + 41 

Amount that Tommy had in the end = 5 u + 30

Amount that Warren had at first 
= 4 u + 41 + 43 + 28
= 4 u + 112

Amount that Will and Tommy had in the end is the same.

4 u + 41 = 5 u + 30
5 u - 4 u = 41 - 30

1 u = 11

Amount that Warren and Will had in the end is the same.

Amount that Warren had in the end
= 4 u + 41
= 4 x 11 + 41
= 44 + 41
= $85

Amount that Warren had at first
= 85 + 43 + 28
= $156

Difference in the amounts between Warren and Will at first
= 156 - 44
= $112

Answer(s): $112
