Amount that Sarah had = $755
Amount that Simon had
= 755 - 622
= $133
Total amount that Sarah and Simon had
= 755 + 133
= $888
Amount that Sarah had in the end = 1 u
Amount that Simon had in the end = 5 u
Total amount that Sarah and Simon had
= 1 u + 5 u
= 6 u
As Sarah gave some money to Simon, the total amount that Simon and Sarah had at first and in the end remains unchanged.
6 u = 888
1 u = 888 ÷ 6 = 148
Amount that Sarah gave Simon
= 755 - 148
= $607
Answer(s): $607
