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