Oscar had $120 more than Cole at first. If Cole had another $120 at first, both of them would had the same amount of money.
6 u - 125 = 1 u + 125 + 120
6 u - 125 = 1 u + 245
6 u - 1 u = 125 + 245
5 u = 370
1 u = 370 ÷ 5 = 74
Amount that Oscar had at first
= 6 u - 125
= 6 x 74 - 125
= 444 - 125
= $319
Answer(s): $319
