Comparing between

in the end |
5x2 =
10 u |
1x2 =
2 u |
$756 |
The amount that Henry had in the end is the repeated. Make the amount that Henry had in the end the same. LCM of 2 and 1 is 2.
12 u = 756
1 u = 756 ÷ 12 = 63
5 u = 5 x 63 = 315
3 p = 756 - 315 = 441
1 p = 441 ÷ 3 = 147
Amount that Andy had at first
= 5 p
= 5 x 147
= $735
Amount that Henry had at first
= 756 - 735
= $21
Answer(s): $21
