Harry, Zane and Brandon went shopping. Harry and Zane spent a total of $300. Harry and Brandon spent $650 altogether. Brandon spent 3 times as much as Zane.
- How much did Zane spend?
- How much did Harry spend?
(a)
Amount that Harry spent = H
Amount that Zane spent = Z
Amount that Brandon spent = B
H + B = 650
H + Z = 300
Z = 1 u
B = 3 x 1 u = 3 u
Amount that Brandon spent more than Zane
= 3 u - 1 u
= 2 u
2 u = 650 - 300
2 u = 350
1 u = 350 ÷ 2 = 175
Amount that Zane spent
= 1 u
= $175
(b)
Amount that Harry spent
= 300 - 175
= $125
Answer(s): (a) $175; (b) $125
