Amount that Lucy had = $709
Amount that Seth had
= 709 - 536
= $173
Total amount that Lucy and Seth had
= 709 + 173
= $882
Amount that Lucy had in the end = 1 u
Amount that Seth had in the end = 5 u
Total amount that Lucy and Seth had
= 1 u + 5 u
= 6 u
As Lucy gave some money to Seth, the total amount that Seth and Lucy had at first and in the end remains unchanged.
6 u = 882
1 u = 882 ÷ 6 = 147
Amount that Lucy gave Seth
= 709 - 147
= $562
Answer(s): $562
