Glen had $146 more than Tommy at first. If Tommy had another $146 at first, both of them would had the same amount of money.
5 u - 139 = 1 u + 139 + 146
5 u - 139 = 1 u + 285
5 u - 1 u = 139 + 285
4 u = 424
1 u = 424 ÷ 4 = 106
Amount that Glen had at first
= 5 u - 139
= 5 x 106 - 139
= 530 - 139
= $391
Answer(s): $391
