Amount that Gillian had = $735
Amount that Peter had
= 735 - 540
= $195
Total amount that Gillian and Peter had
= 735 + 195
= $930
Amount that Gillian had in the end = 1 u
Amount that Peter had in the end = 5 u
Total amount that Gillian and Peter had
= 1 u + 5 u
= 6 u
As Gillian gave some money to Peter, the total amount that Peter and Gillian had at first and in the end remains unchanged.
6 u = 930
1 u = 930 ÷ 6 = 155
Amount that Gillian gave Peter
= 735 - 155
= $580
Answer(s): $580
