Amount that Kathy had = $722
Amount that Jenson had
= 722 - 429
= $293
Total amount that Kathy and Jenson had
= 722 + 293
= $1015
Amount that Kathy had in the end = 1 u
Amount that Jenson had in the end = 4 u
Total amount that Kathy and Jenson had
= 1 u + 4 u
= 5 u
As Kathy gave some money to Jenson, the total amount that Jenson and Kathy had at first and in the end remains unchanged.
5 u = 1015
1 u = 1015 ÷ 5 = 203
Amount that Kathy gave Jenson
= 722 - 203
= $519
Answer(s): $519
