Amount that Roshel had = $904
Amount that Charlie had
= 904 - 503
= $401
Total amount that Roshel and Charlie had
= 904 + 401
= $1305
Amount that Roshel had in the end = 1 u
Amount that Charlie had in the end = 4 u
Total amount that Roshel and Charlie had
= 1 u + 4 u
= 5 u
As Roshel gave some money to Charlie, the total amount that Charlie and Roshel had at first and in the end remains unchanged.
5 u = 1305
1 u = 1305 ÷ 5 = 261
Amount that Roshel gave Charlie
= 904 - 261
= $643
Answer(s): $643
