Gabriel had $156 more than Cole at first. If Cole had another $156 at first, both of them would had the same amount of money.
4 u - 132 = 1 u + 132 + 156
4 u - 132 = 1 u + 288
4 u - 1 u = 132 + 288
3 u = 420
1 u = 420 ÷ 3 = 140
Amount that Gabriel had at first
= 4 u - 132
= 4 x 140 - 132
= 560 - 132
= $428
Answer(s): $428
