Lui, Jack and Harry went shopping. Lui and Jack spent a total of $246. Lui and Harry spent $696 altogether. Harry spent 6 times as much as Jack.
- How much did Jack spend?
- How much did Lui spend?
(a)
Amount that Lui spent = L
Amount that Jack spent = J
Amount that Harry spent = H
L + H = 696
L + J = 246
J = 1 u
H = 6 x 1 u = 6 u
Amount that Harry spent more than Jack
= 6 u - 1 u
= 5 u
5 u = 696 - 246
5 u = 450
1 u = 450 ÷ 5 = 90
Amount that Jack spent
= 1 u
= $90
(b)
Amount that Lui spent
= 246 - 90
= $156
Answer(s): (a) $90; (b) $156
