Amount that Gwen had = $888
Amount that Tim had
= 888 - 405
= $483
Total amount that Gwen and Tim had
= 888 + 483
= $1371
Amount that Gwen had in the end = 1 u
Amount that Tim had in the end = 2 u
Total amount that Gwen and Tim had
= 1 u + 2 u
= 3 u
As Gwen gave some money to Tim, the total amount that Tim and Gwen had at first and in the end remains unchanged.
3 u = 1371
1 u = 1371 ÷ 3 = 457
Amount that Gwen gave Tim
= 888 - 457
= $431
Answer(s): $431
