Cody, Ian and Harry went shopping. Cody and Ian spent a total of $248. Cody and Harry spent $654 altogether. Harry spent 8 times as much as Ian.
- How much did Ian spend?
- How much did Cody spend?
(a)
Amount that Cody spent = C
Amount that Ian spent = I
Amount that Harry spent = H
C + H = 654
C + I = 248
I = 1 u
H = 8 x 1 u = 8 u
Amount that Harry spent more than Ian
= 8 u - 1 u
= 7 u
7 u = 654 - 248
7 u = 406
1 u = 406 ÷ 7 = 58
Amount that Ian spent
= 1 u
= $58
(b)
Amount that Cody spent
= 248 - 58
= $190
Answer(s): (a) $58; (b) $190
