Amount that Sarah had = $846
Amount that Jenson had
= 846 - 487
= $359
Total amount that Sarah and Jenson had
= 846 + 359
= $1205
Amount that Sarah had in the end = 1 u
Amount that Jenson had in the end = 4 u
Total amount that Sarah and Jenson had
= 1 u + 4 u
= 5 u
As Sarah gave some money to Jenson, the total amount that Jenson and Sarah had at first and in the end remains unchanged.
5 u = 1205
1 u = 1205 ÷ 5 = 241
Amount that Sarah gave Jenson
= 846 - 241
= $605
Answer(s): $605
