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