Reggie, Vaidev and Owen went shopping. Reggie and Vaidev spent a total of $285. Reggie and Owen spent $685 altogether. Owen spent 9 times as much as Vaidev.
- How much did Vaidev spend?
- How much did Reggie spend?
(a)
Amount that Reggie spent = R
Amount that Vaidev spent = V
Amount that Owen spent = O
R + O = 685
R + V = 285
V = 1 u
O = 9 x 1 u = 9 u
Amount that Owen spent more than Vaidev
= 9 u - 1 u
= 8 u
8 u = 685 - 285
8 u = 400
1 u = 400 ÷ 8 = 50
Amount that Vaidev spent
= 1 u
= $50
(b)
Amount that Reggie spent
= 285 - 50
= $235
Answer(s): (a) $50; (b) $235
