Amount that Gabby had = $738
Amount that Michael had
= 738 - 512
= $226
Total amount that Gabby and Michael had
= 738 + 226
= $964
Amount that Gabby had in the end = 1 u
Amount that Michael had in the end = 3 u
Total amount that Gabby and Michael had
= 1 u + 3 u
= 4 u
As Gabby gave some money to Michael, the total amount that Michael and Gabby had at first and in the end remains unchanged.
4 u = 964
1 u = 964 ÷ 4 = 241
Amount that Gabby gave Michael
= 738 - 241
= $497
Answer(s): $497
