Eric had $160 more than Ahmad at first. If Ahmad had another $160 at first, both of them would had the same amount of money.
6 u - 120 = 1 u + 120 + 160
6 u - 120 = 1 u + 280
6 u - 1 u = 120 + 280
5 u = 400
1 u = 400 ÷ 5 = 80
Amount that Eric had at first
= 6 u - 120
= 6 x 80 - 120
= 480 - 120
= $360
Answer(s): $360
