Amount that Ivory had = $718
Amount that Jack had
= 718 - 516
= $202
Total amount that Ivory and Jack had
= 718 + 202
= $920
Amount that Ivory had in the end = 1 u
Amount that Jack had in the end = 4 u
Total amount that Ivory and Jack had
= 1 u + 4 u
= 5 u
As Ivory gave some money to Jack, the total amount that Jack and Ivory had at first and in the end remains unchanged.
5 u = 920
1 u = 920 ÷ 5 = 184
Amount that Ivory gave Jack
= 718 - 184
= $534
Answer(s): $534
