The graph shows the amount of savings 3 children had.
- How much money must Xandra give Tiffany so that they will have the same amount of money?
- How much money must Emma give Tiffany so that Tiffany will have $4 more than her?
(a)
Xandra's savings = $54
Tiffany's savings = $12
Difference between Xandra's and Tiffany's savings
= 54 - 12
= $42
Amount that Xandra must give Tiffany
= 42 ÷ 2
= $21
(b)
Total amount of Emma and Tiffany
= 36 + 12
= $48
2 u + 4 = 48
2 u = 48 - 4
2 u = 44
1 u = 44 ÷ 2 = 22
Amount that Emma must give to Tiffany
= 36 - 22
= $14
Answer(s): (a) $21; (b) $14
