Japheth had $156 more than Zane at first. If Zane had another $156 at first, both of them would had the same amount of money.
3 u - 136 = 1 u + 136 + 156
3 u - 136 = 1 u + 292
3 u - 1 u = 136 + 292
2 u = 428
1 u = 428 ÷ 2 = 214
Amount that Japheth had at first
= 3 u - 136
= 3 x 214 - 136
= 642 - 136
= $506
Answer(s): $506
