Jack |
Wendy |
| Before |
7 u |
3 p |
| Change |
- 4 u |
- 1 p |
| After |
3 u |
2 p |
Amount that Jack spent on the pencil = 4 u
4 u = 9.60
1 u = 9.60 ÷ 4 = 2.40
Amount that Jack had at first
= 7 u
= 7 x 2.40
= $16.80
Amount that Wendy had at first
= 16.80 + 59.10
= $75.90
Fraction of money that Wendy had left
= 1 -
13 =
23 Amount that Wendy had at first = 3 p
3 p = 75.90
1 p = 75.90 ÷ 3 = 25.30
Amount that Wendy had left
= 2 p
= 2 x 25.30
= $50.60
Answer(s): $50.60
