Ken, Dylan and Perry went shopping. Ken and Dylan spent a total of $267. Ken and Perry spent $612 altogether. Perry spent 6 times as much as Dylan.
- How much did Dylan spend?
- How much did Ken spend?
(a)
Amount that Ken spent = K
Amount that Dylan spent = D
Amount that Perry spent = P
K + P = 612
K + D = 267
D = 1 u
P = 6 x 1 u = 6 u
Amount that Perry spent more than Dylan
= 6 u - 1 u
= 5 u
5 u = 612 - 267
5 u = 345
1 u = 345 ÷ 5 = 69
Amount that Dylan spent
= 1 u
= $69
(b)
Amount that Ken spent
= 267 - 69
= $198
Answer(s): (a) $69; (b) $198
