Gabriel, Dylan and Luke went shopping. Gabriel and Dylan spent a total of $227. Gabriel and Luke spent $629 altogether. Luke spent 4 times as much as Dylan.
- How much did Dylan spend?
- How much did Gabriel spend?
(a)
Amount that Gabriel spent = G
Amount that Dylan spent = D
Amount that Luke spent = L
G + L = 629
G + D = 227
D = 1 u
L = 4 x 1 u = 4 u
Amount that Luke spent more than Dylan
= 4 u - 1 u
= 3 u
3 u = 629 - 227
3 u = 402
1 u = 402 ÷ 3 = 134
Amount that Dylan spent
= 1 u
= $134
(b)
Amount that Gabriel spent
= 227 - 134
= $93
Answer(s): (a) $134; (b) $93
