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