Harry had $134 more than Archie at first. If Archie had another $134 at first, both of them would had the same amount of money.
4 u - 128 = 1 u + 128 + 134
4 u - 128 = 1 u + 262
4 u - 1 u = 128 + 262
3 u = 390
1 u = 390 ÷ 3 = 130
Amount that Harry had at first
= 4 u - 128
= 4 x 130 - 128
= 520 - 128
= $392
Answer(s): $392
