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