The graph shows the amount of savings 3 children had.
- How much money must Penelope give Lucy so that they will have the same amount of money?
- How much money must Emma give Lucy so that Lucy will have $2 more than her?
(a)
Penelope's savings = $72
Lucy's savings = $16
Difference between Penelope's and Lucy's savings
= 72 - 16
= $56
Amount that Penelope must give Lucy
= 56 ÷ 2
= $28
(b)
Total amount of Emma and Lucy
= 48 + 16
= $64
2 u + 2 = 64
2 u = 64 - 2
2 u = 62
1 u = 62 ÷ 2 = 31
Amount that Emma must give to Lucy
= 48 - 31
= $17
Answer(s): (a) $28; (b) $17
