The graph shows the amount of savings 3 children had.
- How much money must Sarah give Victoria so that they will have the same amount of money?
- How much money must Barbara give Victoria so that Victoria will have $4 more than her?
(a)
Sarah's savings = $36
Victoria's savings = $8
Difference between Sarah's and Victoria's savings
= 36 - 8
= $28
Amount that Sarah must give Victoria
= 28 ÷ 2
= $14
(b)
Total amount of Barbara and Victoria
= 24 + 8
= $32
2 u + 4 = 32
2 u = 32 - 4
2 u = 28
1 u = 28 ÷ 2 = 14
Amount that Barbara must give to Victoria
= 24 - 14
= $10
Answer(s): (a) $14; (b) $10
