Amount that Elyse had = $822
Amount that Sean had
= 822 - 624
= $198
Total amount that Elyse and Sean had
= 822 + 198
= $1020
Amount that Elyse had in the end = 1 u
Amount that Sean had in the end = 4 u
Total amount that Elyse and Sean had
= 1 u + 4 u
= 5 u
As Elyse gave some money to Sean, the total amount that Sean and Elyse had at first and in the end remains unchanged.
5 u = 1020
1 u = 1020 ÷ 5 = 204
Amount that Elyse gave Sean
= 822 - 204
= $618
Answer(s): $618
