Comparing between

in the end |
4x2 =
8 u |
1x2 =
2 u |
$390 |
The amount that Carl had in the end is the repeated. Make the amount that Carl had in the end the same. LCM of 2 and 1 is 2.
10 u = 390
1 u = 390 ÷ 10 = 39
5 u = 5 x 39 = 195
3 p = 390 - 195 = 195
1 p = 195 ÷ 3 = 65
Amount that Wesley had at first
= 5 p
= 5 x 65
= $325
Amount that Carl had at first
= 390 - 325
= $65
Answer(s): $65
