The graph shows the amount of savings 3 children had.
- How much money must Irene give Jade so that they will have the same amount of money?
- How much money must Penelope give Jade so that Jade will have $4 more than her?
(a)
Irene's savings = $90
Jade's savings = $20
Difference between Irene's and Jade's savings
= 90 - 20
= $70
Amount that Irene must give Jade
= 70 ÷ 2
= $35
(b)
Total amount of Penelope and Jade
= 60 + 20
= $80
2 u + 4 = 80
2 u = 80 - 4
2 u = 76
1 u = 76 ÷ 2 = 38
Amount that Penelope must give to Jade
= 60 - 38
= $22
Answer(s): (a) $35; (b) $22
