Amount that Cathy had = $803
Amount that Xavier had
= 803 - 478
= $325
Total amount that Cathy and Xavier had
= 803 + 325
= $1128
Amount that Cathy had in the end = 1 u
Amount that Xavier had in the end = 5 u
Total amount that Cathy and Xavier had
= 1 u + 5 u
= 6 u
As Cathy gave some money to Xavier, the total amount that Xavier and Cathy had at first and in the end remains unchanged.
6 u = 1128
1 u = 1128 ÷ 6 = 188
Amount that Cathy gave Xavier
= 803 - 188
= $615
Answer(s): $615
