The graph shows the amount of savings 3 children had.
- How much money must Wendy give Vanessa so that they will have the same amount of money?
- How much money must Sarah give Vanessa so that Vanessa will have $4 more than her?
(a)
Wendy's savings = $18
Vanessa's savings = $4
Difference between Wendy's and Vanessa's savings
= 18 - 4
= $14
Amount that Wendy must give Vanessa
= 14 ÷ 2
= $7
(b)
Total amount of Sarah and Vanessa
= 12 + 4
= $16
2 u + 4 = 16
2 u = 16 - 4
2 u = 12
1 u = 12 ÷ 2 = 6
Amount that Sarah must give to Vanessa
= 12 - 6
= $6
Answer(s): (a) $7; (b) $6
