Paul had $136 more than Oliver at first. If Oliver had another $136 at first, both of them would had the same amount of money.
5 u - 140 = 1 u + 140 + 136
5 u - 140 = 1 u + 276
5 u - 1 u = 140 + 276
4 u = 416
1 u = 416 ÷ 4 = 104
Amount that Paul had at first
= 5 u - 140
= 5 x 104 - 140
= 520 - 140
= $380
Answer(s): $380
