The graph shows the amount of savings 3 children had.
- How much money must Betty give Min so that they will have the same amount of money?
- How much money must Jade give Min so that Min will have $2 more than her?
(a)
Betty's savings = $18
Min's savings = $4
Difference between Betty's and Min's savings
= 18 - 4
= $14
Amount that Betty must give Min
= 14 ÷ 2
= $7
(b)
Total amount of Jade and Min
= 12 + 4
= $16
2 u + 2 = 16
2 u = 16 - 2
2 u = 14
1 u = 14 ÷ 2 = 7
Amount that Jade must give to Min
= 12 - 7
= $5
Answer(s): (a) $7; (b) $5
