Amount that Anna had = $880
Amount that Archie had
= 880 - 608
= $272
Total amount that Anna and Archie had
= 880 + 272
= $1152
Amount that Anna had in the end = 1 u
Amount that Archie had in the end = 2 u
Total amount that Anna and Archie had
= 1 u + 2 u
= 3 u
As Anna gave some money to Archie, the total amount that Archie and Anna had at first and in the end remains unchanged.
3 u = 1152
1 u = 1152 ÷ 3 = 384
Amount that Anna gave Archie
= 880 - 384
= $496
Answer(s): $496
