Harry had $158 more than Ahmad at first. If Ahmad had another $158 at first, both of them would had the same amount of money.
5 u - 131 = 1 u + 131 + 158
5 u - 131 = 1 u + 289
5 u - 1 u = 131 + 289
4 u = 420
1 u = 420 ÷ 4 = 105
Amount that Harry had at first
= 5 u - 131
= 5 x 105 - 131
= 525 - 131
= $394
Answer(s): $394
