Will had $138 more than Ben at first. If Ben had another $138 at first, both of them would had the same amount of money.
5 u - 125 = 1 u + 125 + 138
5 u - 125 = 1 u + 263
5 u - 1 u = 125 + 263
4 u = 388
1 u = 388 ÷ 4 = 97
Amount that Will had at first
= 5 u - 125
= 5 x 97 - 125
= 485 - 125
= $360
Answer(s): $360
