Ken, Harry and Gabriel went shopping. Ken and Harry spent a total of $252. Ken and Gabriel spent $630 altogether. Gabriel spent 7 times as much as Harry.
- How much did Harry spend?
- How much did Ken spend?
(a)
Amount that Ken spent = K
Amount that Harry spent = H
Amount that Gabriel spent = G
K + G = 630
K + H = 252
H = 1 u
G = 7 x 1 u = 7 u
Amount that Gabriel spent more than Harry
= 7 u - 1 u
= 6 u
6 u = 630 - 252
6 u = 378
1 u = 378 ÷ 6 = 63
Amount that Harry spent
= 1 u
= $63
(b)
Amount that Ken spent
= 252 - 63
= $189
Answer(s): (a) $63; (b) $189
