Comparing Wesley

4 u |
1 u |
$150 |
The total amount that Perry and Wesley had remains unchanged.
Total amount in the end
= 4 u + 1 u
= 5 u
5 u = 150
1 u = 150 ÷ 5 = 30
Amount that Wesley has in the end
= 4 u
= 4 x 30
= $120
Amount that Perry has in the end
= 1 u
= $30
6 p = 1 u = 30
1 p = 30 ÷ 6 = 5
Amount that Perry gave to Wesley
= 1 p
= 1 x 5
= $5
Amount that Wesley had at first
= 120 - 5 + 10
= $125
Answer(s): $125
