Amount that Xandra had = $712
Amount that Brandon had
= 712 - 594
= $118
Total amount that Xandra and Brandon had
= 712 + 118
= $830
Amount that Xandra had in the end = 1 u
Amount that Brandon had in the end = 4 u
Total amount that Xandra and Brandon had
= 1 u + 4 u
= 5 u
As Xandra gave some money to Brandon, the total amount that Brandon and Xandra had at first and in the end remains unchanged.
5 u = 830
1 u = 830 ÷ 5 = 166
Amount that Xandra gave Brandon
= 712 - 166
= $546
Answer(s): $546
