Three schoolmates spent a total of $64. Lynn spent $7 more than Jade and Winnie spent $14 more than Lynn.
- How much money did Jade spend?
- How much money did Winnie spend?
(a)
Amount that Jade spent = 1 u
Amount that Lynn spent = 1 u + 7
Amount that Winnie spent = 1 u + 7 + 14 = 1 u + 21
Total amount that they spent
= 1 u + 1 u + 7 + 1 u + 21
= 3 u + 28
3 u + 28 = 64
3 u = 64 - 28
3 u = 36
1 u = 36 ÷ 3 = $12
Amount that Jade spent
= 1 u
= 12
(b)
Amount that Winnie spent
= 1 u + 21
= 12 + 21
= $33
Answer(s): (a) $12; (b) $33
