Luke had $146 more than Harry at first. If Harry had another $146 at first, both of them would had the same amount of money.
3 u - 140 = 1 u + 140 + 146
3 u - 140 = 1 u + 286
3 u - 1 u = 140 + 286
2 u = 426
1 u = 426 ÷ 2 = 213
Amount that Luke had at first
= 3 u - 140
= 3 x 213 - 140
= 639 - 140
= $499
Answer(s): $499
