Amount that Elyse had = $880
Amount that Zeph had
= 880 - 641
= $239
Total amount that Elyse and Zeph had
= 880 + 239
= $1119
Amount that Elyse had in the end = 1 u
Amount that Zeph had in the end = 2 u
Total amount that Elyse and Zeph had
= 1 u + 2 u
= 3 u
As Elyse gave some money to Zeph, the total amount that Zeph and Elyse had at first and in the end remains unchanged.
3 u = 1119
1 u = 1119 ÷ 3 = 373
Amount that Elyse gave Zeph
= 880 - 373
= $507
Answer(s): $507
