Reggie had $129 more than Ethan at first. If Ethan had another $129 at first, both of them would had the same amount of money.
6 u - 128 = 1 u + 128 + 129
6 u - 128 = 1 u + 257
6 u - 1 u = 128 + 257
5 u = 385
1 u = 385 ÷ 5 = 77
Amount that Reggie had at first
= 6 u - 128
= 6 x 77 - 128
= 462 - 128
= $334
Answer(s): $334
