Amount that Usha had = $921
Amount that Fabian had
= 921 - 504
= $417
Total amount that Usha and Fabian had
= 921 + 417
= $1338
Amount that Usha had in the end = 1 u
Amount that Fabian had in the end = 2 u
Total amount that Usha and Fabian had
= 1 u + 2 u
= 3 u
As Usha gave some money to Fabian, the total amount that Fabian and Usha had at first and in the end remains unchanged.
3 u = 1338
1 u = 1338 ÷ 3 = 446
Amount that Usha gave Fabian
= 921 - 446
= $475
Answer(s): $475
