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