Amount that Xylia had = $730
Amount that Simon had
= 730 - 640
= $90
Total amount that Xylia and Simon had
= 730 + 90
= $820
Amount that Xylia had in the end = 1 u
Amount that Simon had in the end = 3 u
Total amount that Xylia and Simon had
= 1 u + 3 u
= 4 u
As Xylia gave some money to Simon, the total amount that Simon and Xylia had at first and in the end remains unchanged.
4 u = 820
1 u = 820 ÷ 4 = 205
Amount that Xylia gave Simon
= 730 - 205
= $525
Answer(s): $525
