Fred, Glen and Eric went shopping. Fred and Glen spent a total of $246. Fred and Eric spent $638 altogether. Eric spent 5 times as much as Glen.
- How much did Glen spend?
- How much did Fred spend?
(a)
Amount that Fred spent = F
Amount that Glen spent = G
Amount that Eric spent = E
F + E = 638
F + G = 246
G = 1 u
E = 5 x 1 u = 5 u
Amount that Eric spent more than Glen
= 5 u - 1 u
= 4 u
4 u = 638 - 246
4 u = 392
1 u = 392 ÷ 4 = 98
Amount that Glen spent
= 1 u
= $98
(b)
Amount that Fred spent
= 246 - 98
= $148
Answer(s): (a) $98; (b) $148
