The graph shows the amount of savings 3 children had.
- How much money must Xandra give Shiyun so that they will have the same amount of money?
- How much money must Gillian give Shiyun so that Shiyun will have $2 more than her?
(a)
Xandra's savings = $54
Shiyun's savings = $12
Difference between Xandra's and Shiyun's savings
= 54 - 12
= $42
Amount that Xandra must give Shiyun
= 42 ÷ 2
= $21
(b)
Total amount of Gillian and Shiyun
= 36 + 12
= $48
2 u + 2 = 48
2 u = 48 - 2
2 u = 46
1 u = 46 ÷ 2 = 23
Amount that Gillian must give to Shiyun
= 36 - 23
= $13
Answer(s): (a) $21; (b) $13
