Perry had $145 more than Henry at first. If Henry had another $145 at first, both of them would had the same amount of money.
4 u - 133 = 1 u + 133 + 145
4 u - 133 = 1 u + 278
4 u - 1 u = 133 + 278
3 u = 411
1 u = 411 ÷ 3 = 137
Amount that Perry had at first
= 4 u - 133
= 4 x 137 - 133
= 548 - 133
= $415
Answer(s): $415
