Warren had $150 more than Ben at first. If Ben had another $150 at first, both of them would had the same amount of money.
5 u - 137 = 1 u + 137 + 150
5 u - 137 = 1 u + 287
5 u - 1 u = 137 + 287
4 u = 424
1 u = 424 ÷ 4 = 106
Amount that Warren had at first
= 5 u - 137
= 5 x 106 - 137
= 530 - 137
= $393
Answer(s): $393
