Ahmad had $150 more than Justin at first. If Justin had another $150 at first, both of them would had the same amount of money.
6 u - 125 = 1 u + 125 + 150
6 u - 125 = 1 u + 275
6 u - 1 u = 125 + 275
5 u = 400
1 u = 400 ÷ 5 = 80
Amount that Ahmad had at first
= 6 u - 125
= 6 x 80 - 125
= 480 - 125
= $355
Answer(s): $355
