Gabriel, Ahmad and Sean went shopping. Gabriel and Ahmad spent a total of $295. Gabriel and Sean spent $640 altogether. Sean spent 6 times as much as Ahmad.
- How much did Ahmad spend?
- How much did Gabriel spend?
(a)
Amount that Gabriel spent = G
Amount that Ahmad spent = A
Amount that Sean spent = S
G + S = 640
G + A = 295
A = 1 u
S = 6 x 1 u = 6 u
Amount that Sean spent more than Ahmad
= 6 u - 1 u
= 5 u
5 u = 640 - 295
5 u = 345
1 u = 345 ÷ 5 = 69
Amount that Ahmad spent
= 1 u
= $69
(b)
Amount that Gabriel spent
= 295 - 69
= $226
Answer(s): (a) $69; (b) $226
