The graph shows the amount of savings 3 children had.
- How much money must Jade give Tiffany so that they will have the same amount of money?
- How much money must Barbara give Tiffany so that Tiffany will have $4 more than her?
(a)
Jade's savings = $54
Tiffany's savings = $12
Difference between Jade's and Tiffany's savings
= 54 - 12
= $42
Amount that Jade must give Tiffany
= 42 ÷ 2
= $21
(b)
Total amount of Barbara and Tiffany
= 36 + 12
= $48
2 u + 4 = 48
2 u = 48 - 4
2 u = 44
1 u = 44 ÷ 2 = 22
Amount that Barbara must give to Tiffany
= 36 - 22
= $14
Answer(s): (a) $21; (b) $14
