Reggie, Ahmad and Xavier went shopping. Reggie and Ahmad spent a total of $281. Reggie and Xavier spent $689 altogether. Xavier spent 9 times as much as Ahmad.
- How much did Ahmad spend?
- How much did Reggie spend?
(a)
Amount that Reggie spent = R
Amount that Ahmad spent = A
Amount that Xavier spent = X
R + X = 689
R + A = 281
A = 1 u
X = 9 x 1 u = 9 u
Amount that Xavier spent more than Ahmad
= 9 u - 1 u
= 8 u
8 u = 689 - 281
8 u = 408
1 u = 408 ÷ 8 = 51
Amount that Ahmad spent
= 1 u
= $51
(b)
Amount that Reggie spent
= 281 - 51
= $230
Answer(s): (a) $51; (b) $230
