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