Amount that Abi had = $981
Amount that Vincent had
= 981 - 486
= $495
Total amount that Abi and Vincent had
= 981 + 495
= $1476
Amount that Abi had in the end = 1 u
Amount that Vincent had in the end = 3 u
Total amount that Abi and Vincent had
= 1 u + 3 u
= 4 u
As Abi gave some money to Vincent, the total amount that Vincent and Abi had at first and in the end remains unchanged.
4 u = 1476
1 u = 1476 ÷ 4 = 369
Amount that Abi gave Vincent
= 981 - 369
= $612
Answer(s): $612
