(a)
Lee had $180 more than Ben at first. If Ben received another $180, Lee and Ben would have the same amount at first.
5 u + 60 = 3 u - 60 + 180
5 u + 60 = 3 u + 120
5 u - 3 u = 120 - 60
2 u = 60
1 u = 60 ÷ 2 = 30
Amount that Lee had at first
= 5 u + 60
= 5 x 30 + 60
= 150 + 60
= $210
(b)
Amount that Ben had at first
= 3 u - 60
= 3 x 30 - 60
= 90 - 60
= $30
Answer(s): (a) $210; (b) $30
