(a)
Valen had $330 more than Oscar at first. If Oscar received another $330, Valen and Oscar would have the same amount at first.
5 u + 60 = 2 u - 60 + 330
5 u + 60 = 2 u + 270
5 u - 2 u = 270 - 60
3 u = 210
1 u = 210 ÷ 3 = 70
Amount that Valen had at first
= 5 u + 60
= 5 x 70 + 60
= 350 + 60
= $410
(b)
Amount that Oscar had at first
= 2 u - 60
= 2 x 70 - 60
= 140 - 60
= $80
Answer(s): (a) $410; (b) $80
