Ken, Peter and Dylan went shopping. Ken and Peter spent a total of $207. Ken and Dylan spent $672 altogether. Dylan spent 6 times as much as Peter.
- How much did Peter spend?
- How much did Ken spend?
(a)
Amount that Ken spent = K
Amount that Peter spent = P
Amount that Dylan spent = D
K + D = 672
K + P = 207
P = 1 u
D = 6 x 1 u = 6 u
Amount that Dylan spent more than Peter
= 6 u - 1 u
= 5 u
5 u = 672 - 207
5 u = 465
1 u = 465 ÷ 5 = 93
Amount that Peter spent
= 1 u
= $93
(b)
Amount that Ken spent
= 207 - 93
= $114
Answer(s): (a) $93; (b) $114
