The graph shows the amount of savings 3 children had.
- How much money must Dana give Xylia so that they will have the same amount of money?
- How much money must Cindy give Xylia so that Xylia will have $4 more than her?
(a)
Dana's savings = $72
Xylia's savings = $16
Difference between Dana's and Xylia's savings
= 72 - 16
= $56
Amount that Dana must give Xylia
= 56 ÷ 2
= $28
(b)
Total amount of Cindy and Xylia
= 48 + 16
= $64
2 u + 4 = 64
2 u = 64 - 4
2 u = 60
1 u = 60 ÷ 2 = 30
Amount that Cindy must give to Xylia
= 48 - 30
= $18
Answer(s): (a) $28; (b) $18
