Vaidev, Carl and Neave went shopping. Vaidev and Carl spent a total of $236. Vaidev and Neave spent $677 altogether. Neave spent 8 times as much as Carl.
- How much did Carl spend?
- How much did Vaidev spend?
(a)
Amount that Vaidev spent = V
Amount that Carl spent = C
Amount that Neave spent = N
V + N = 677
V + C = 236
C = 1 u
N = 8 x 1 u = 8 u
Amount that Neave spent more than Carl
= 8 u - 1 u
= 7 u
7 u = 677 - 236
7 u = 441
1 u = 441 ÷ 7 = 63
Amount that Carl spent
= 1 u
= $63
(b)
Amount that Vaidev spent
= 236 - 63
= $173
Answer(s): (a) $63; (b) $173
