Charlie had $131 more than Fabian at first. If Fabian had another $131 at first, both of them would had the same amount of money.
4 u - 134 = 1 u + 134 + 131
4 u - 134 = 1 u + 265
4 u - 1 u = 134 + 265
3 u = 399
1 u = 399 ÷ 3 = 133
Amount that Charlie had at first
= 4 u - 134
= 4 x 133 - 134
= 532 - 134
= $398
Answer(s): $398
