Howard, Pierre and Dylan went shopping. Howard and Pierre spent a total of $230. Howard and Dylan spent $635 altogether. Dylan spent 4 times as much as Pierre.
- How much did Pierre spend?
- How much did Howard spend?
(a)
Amount that Howard spent = H
Amount that Pierre spent = P
Amount that Dylan spent = D
H + D = 635
H + P = 230
P = 1 u
D = 4 x 1 u = 4 u
Amount that Dylan spent more than Pierre
= 4 u - 1 u
= 3 u
3 u = 635 - 230
3 u = 405
1 u = 405 ÷ 3 = 135
Amount that Pierre spent
= 1 u
= $135
(b)
Amount that Howard spent
= 230 - 135
= $95
Answer(s): (a) $135; (b) $95
