Brandon, Reggie and Archie went shopping. Brandon and Reggie spent a total of $269. Brandon and Archie spent $605 altogether. Archie spent 4 times as much as Reggie.
- How much did Reggie spend?
- How much did Brandon spend?
(a)
Amount that Brandon spent = B
Amount that Reggie spent = R
Amount that Archie spent = A
B + A = 605
B + R = 269
R = 1 u
A = 4 x 1 u = 4 u
Amount that Archie spent more than Reggie
= 4 u - 1 u
= 3 u
3 u = 605 - 269
3 u = 336
1 u = 336 ÷ 3 = 112
Amount that Reggie spent
= 1 u
= $112
(b)
Amount that Brandon spent
= 269 - 112
= $157
Answer(s): (a) $112; (b) $157
