Amount that Sabrina had = $905
Amount that George had
= 905 - 613
= $292
Total amount that Sabrina and George had
= 905 + 292
= $1197
Amount that Sabrina had in the end = 1 u
Amount that George had in the end = 2 u
Total amount that Sabrina and George had
= 1 u + 2 u
= 3 u
As Sabrina gave some money to George, the total amount that George and Sabrina had at first and in the end remains unchanged.
3 u = 1197
1 u = 1197 ÷ 3 = 399
Amount that Sabrina gave George
= 905 - 399
= $506
Answer(s): $506
