Will, Oliver and Albert went shopping. Will and Oliver spent a total of $241. Will and Albert spent $677 altogether. Albert spent 3 times as much as Oliver.
- How much did Oliver spend?
- How much did Will spend?
(a)
Amount that Will spent = W
Amount that Oliver spent = O
Amount that Albert spent = A
W + A = 677
W + O = 241
O = 1 u
A = 3 x 1 u = 3 u
Amount that Albert spent more than Oliver
= 3 u - 1 u
= 2 u
2 u = 677 - 241
2 u = 436
1 u = 436 ÷ 2 = 218
Amount that Oliver spent
= 1 u
= $218
(b)
Amount that Will spent
= 241 - 218
= $23
Answer(s): (a) $218; (b) $23
