Sean had $160 more than Peter at first. If Peter had another $160 at first, both of them would had the same amount of money.
5 u - 126 = 1 u + 126 + 160
5 u - 126 = 1 u + 286
5 u - 1 u = 126 + 286
4 u = 412
1 u = 412 ÷ 4 = 103
Amount that Sean had at first
= 5 u - 126
= 5 x 103 - 126
= 515 - 126
= $389
Answer(s): $389
