Amount that Anna had = $748
Amount that Glen had
= 748 - 491
= $257
Total amount that Anna and Glen had
= 748 + 257
= $1005
Amount that Anna had in the end = 1 u
Amount that Glen had in the end = 2 u
Total amount that Anna and Glen had
= 1 u + 2 u
= 3 u
As Anna gave some money to Glen, the total amount that Glen and Anna had at first and in the end remains unchanged.
3 u = 1005
1 u = 1005 ÷ 3 = 335
Amount that Anna gave Glen
= 748 - 335
= $413
Answer(s): $413
