Henry, Vincent and Billy went shopping. Henry and Vincent spent a total of $283. Henry and Billy spent $647 altogether. Billy spent 3 times as much as Vincent.
- How much did Vincent spend?
- How much did Henry spend?
(a)
Amount that Henry spent = H
Amount that Vincent spent = V
Amount that Billy spent = B
H + B = 647
H + V = 283
V = 1 u
B = 3 x 1 u = 3 u
Amount that Billy spent more than Vincent
= 3 u - 1 u
= 2 u
2 u = 647 - 283
2 u = 364
1 u = 364 ÷ 2 = 182
Amount that Vincent spent
= 1 u
= $182
(b)
Amount that Henry spent
= 283 - 182
= $101
Answer(s): (a) $182; (b) $101
