Reggie, Mark and Cody went shopping. Reggie and Mark spent a total of $226. Reggie and Cody spent $628 altogether. Cody spent 3 times as much as Mark.
- How much did Mark spend?
- How much did Reggie spend?
(a)
Amount that Reggie spent = R
Amount that Mark spent = M
Amount that Cody spent = C
R + C = 628
R + M = 226
M = 1 u
C = 3 x 1 u = 3 u
Amount that Cody spent more than Mark
= 3 u - 1 u
= 2 u
2 u = 628 - 226
2 u = 402
1 u = 402 ÷ 2 = 201
Amount that Mark spent
= 1 u
= $201
(b)
Amount that Reggie spent
= 226 - 201
= $25
Answer(s): (a) $201; (b) $25
