Wesley, Ken and Asher went shopping. Wesley and Ken spent a total of $230. Wesley and Asher spent $610 altogether. Asher spent 3 times as much as Ken.
- How much did Ken spend?
- How much did Wesley spend?
(a)
Amount that Wesley spent = W
Amount that Ken spent = K
Amount that Asher spent = A
W + A = 610
W + K = 230
K = 1 u
A = 3 x 1 u = 3 u
Amount that Asher spent more than Ken
= 3 u - 1 u
= 2 u
2 u = 610 - 230
2 u = 380
1 u = 380 ÷ 2 = 190
Amount that Ken spent
= 1 u
= $190
(b)
Amount that Wesley spent
= 230 - 190
= $40
Answer(s): (a) $190; (b) $40
