Oscar, Fred and Justin went shopping. Oscar and Fred spent a total of $265. Oscar and Justin spent $620 altogether. Justin spent 6 times as much as Fred.
- How much did Fred spend?
- How much did Oscar spend?
(a)
Amount that Oscar spent = O
Amount that Fred spent = F
Amount that Justin spent = J
O + J = 620
O + F = 265
F = 1 u
J = 6 x 1 u = 6 u
Amount that Justin spent more than Fred
= 6 u - 1 u
= 5 u
5 u = 620 - 265
5 u = 355
1 u = 355 ÷ 5 = 71
Amount that Fred spent
= 1 u
= $71
(b)
Amount that Oscar spent
= 265 - 71
= $194
Answer(s): (a) $71; (b) $194
