Amount that Joelle had = $719
Amount that Pierre had
= 719 - 454
= $265
Total amount that Joelle and Pierre had
= 719 + 265
= $984
Amount that Joelle had in the end = 1 u
Amount that Pierre had in the end = 3 u
Total amount that Joelle and Pierre had
= 1 u + 3 u
= 4 u
As Joelle gave some money to Pierre, the total amount that Pierre and Joelle had at first and in the end remains unchanged.
4 u = 984
1 u = 984 ÷ 4 = 246
Amount that Joelle gave Pierre
= 719 - 246
= $473
Answer(s): $473
