Cole had $142 more than Paul at first. If Paul had another $142 at first, both of them would had the same amount of money.
6 u - 139 = 1 u + 139 + 142
6 u - 139 = 1 u + 281
6 u - 1 u = 139 + 281
5 u = 420
1 u = 420 ÷ 5 = 84
Amount that Cole had at first
= 6 u - 139
= 6 x 84 - 139
= 504 - 139
= $365
Answer(s): $365
