Amount that Xuan had = $893
Amount that John had
= 893 - 436
= $457
Total amount that Xuan and John had
= 893 + 457
= $1350
Amount that Xuan had in the end = 1 u
Amount that John had in the end = 5 u
Total amount that Xuan and John had
= 1 u + 5 u
= 6 u
As Xuan gave some money to John, the total amount that John and Xuan had at first and in the end remains unchanged.
6 u = 1350
1 u = 1350 ÷ 6 = 225
Amount that Xuan gave John
= 893 - 225
= $668
Answer(s): $668
