Amount that Fiona had = $881
Amount that Pierre had
= 881 - 595
= $286
Total amount that Fiona and Pierre had
= 881 + 286
= $1167
Amount that Fiona had in the end = 1 u
Amount that Pierre had in the end = 2 u
Total amount that Fiona and Pierre had
= 1 u + 2 u
= 3 u
As Fiona gave some money to Pierre, the total amount that Pierre and Fiona had at first and in the end remains unchanged.
3 u = 1167
1 u = 1167 ÷ 3 = 389
Amount that Fiona gave Pierre
= 881 - 389
= $492
Answer(s): $492
