Amount that Nicole had = $822
Amount that Pierre had
= 822 - 540
= $282
Total amount that Nicole and Pierre had
= 822 + 282
= $1104
Amount that Nicole had in the end = 1 u
Amount that Pierre had in the end = 2 u
Total amount that Nicole and Pierre had
= 1 u + 2 u
= 3 u
As Nicole gave some money to Pierre, the total amount that Pierre and Nicole had at first and in the end remains unchanged.
3 u = 1104
1 u = 1104 ÷ 3 = 368
Amount that Nicole gave Pierre
= 822 - 368
= $454
Answer(s): $454
