Sean, Andy and Eric went shopping. Sean and Andy spent a total of $226. Sean and Eric spent $619 altogether. Eric spent 4 times as much as Andy.
- How much did Andy spend?
- How much did Sean spend?
(a)
Amount that Sean spent = S
Amount that Andy spent = A
Amount that Eric spent = E
S + E = 619
S + A = 226
A = 1 u
E = 4 x 1 u = 4 u
Amount that Eric spent more than Andy
= 4 u - 1 u
= 3 u
3 u = 619 - 226
3 u = 393
1 u = 393 ÷ 3 = 131
Amount that Andy spent
= 1 u
= $131
(b)
Amount that Sean spent
= 226 - 131
= $95
Answer(s): (a) $131; (b) $95
