The graph shows the amount of savings 3 children had.
- How much money must Fanny give Xandra so that they will have the same amount of money?
- How much money must Zoe give Xandra so that Xandra will have $4 more than her?
(a)
Fanny's savings = $36
Xandra's savings = $8
Difference between Fanny's and Xandra's savings
= 36 - 8
= $28
Amount that Fanny must give Xandra
= 28 ÷ 2
= $14
(b)
Total amount of Zoe and Xandra
= 24 + 8
= $32
2 u + 4 = 32
2 u = 32 - 4
2 u = 28
1 u = 28 ÷ 2 = 14
Amount that Zoe must give to Xandra
= 24 - 14
= $10
Answer(s): (a) $14; (b) $10
