Albert had $124 more than Sam at first. If Sam had another $124 at first, both of them would had the same amount of money.
3 u - 134 = 1 u + 134 + 124
3 u - 134 = 1 u + 258
3 u - 1 u = 134 + 258
2 u = 392
1 u = 392 ÷ 2 = 196
Amount that Albert had at first
= 3 u - 134
= 3 x 196 - 134
= 588 - 134
= $454
Answer(s): $454
