Amount that Gillian had = $923
Amount that Charlie had
= 923 - 565
= $358
Total amount that Gillian and Charlie had
= 923 + 358
= $1281
Amount that Gillian had in the end = 1 u
Amount that Charlie had in the end = 2 u
Total amount that Gillian and Charlie had
= 1 u + 2 u
= 3 u
As Gillian gave some money to Charlie, the total amount that Charlie and Gillian had at first and in the end remains unchanged.
3 u = 1281
1 u = 1281 ÷ 3 = 427
Amount that Gillian gave Charlie
= 923 - 427
= $496
Answer(s): $496
