Amount that Ivory had = $812
Amount that Liam had
= 812 - 631
= $181
Total amount that Ivory and Liam had
= 812 + 181
= $993
Amount that Ivory had in the end = 1 u
Amount that Liam had in the end = 2 u
Total amount that Ivory and Liam had
= 1 u + 2 u
= 3 u
As Ivory gave some money to Liam, the total amount that Liam and Ivory had at first and in the end remains unchanged.
3 u = 993
1 u = 993 ÷ 3 = 331
Amount that Ivory gave Liam
= 812 - 331
= $481
Answer(s): $481
