Neave, Sean and Jeremy went shopping. Neave and Sean spent a total of $243. Neave and Jeremy spent $658 altogether. Jeremy spent 6 times as much as Sean.
- How much did Sean spend?
- How much did Neave spend?
(a)
Amount that Neave spent = N
Amount that Sean spent = S
Amount that Jeremy spent = J
N + J = 658
N + S = 243
S = 1 u
J = 6 x 1 u = 6 u
Amount that Jeremy spent more than Sean
= 6 u - 1 u
= 5 u
5 u = 658 - 243
5 u = 415
1 u = 415 ÷ 5 = 83
Amount that Sean spent
= 1 u
= $83
(b)
Amount that Neave spent
= 243 - 83
= $160
Answer(s): (a) $83; (b) $160
