Sean had $141 more than Ben at first. If Ben had another $141 at first, both of them would had the same amount of money.
4 u - 132 = 1 u + 132 + 141
4 u - 132 = 1 u + 273
4 u - 1 u = 132 + 273
3 u = 405
1 u = 405 ÷ 3 = 135
Amount that Sean had at first
= 4 u - 132
= 4 x 135 - 132
= 540 - 132
= $408
Answer(s): $408
