The graph shows the amount of savings 3 children had.
- How much money must Linda give Julie so that they will have the same amount of money?
- How much money must Jade give Julie so that Julie will have $2 more than her?
(a)
Linda's savings = $90
Julie's savings = $20
Difference between Linda's and Julie's savings
= 90 - 20
= $70
Amount that Linda must give Julie
= 70 ÷ 2
= $35
(b)
Total amount of Jade and Julie
= 60 + 20
= $80
2 u + 2 = 80
2 u = 80 - 2
2 u = 78
1 u = 78 ÷ 2 = 39
Amount that Jade must give to Julie
= 60 - 39
= $21
Answer(s): (a) $35; (b) $21
