| |
Paul |
Winnie |
| Before |
8 u |
7 p |
| Change |
- 7 u |
- 4 p |
| After |
1 u |
3 p |
Amount that Paul spent on the pen = 7 u
7 u = 19.60
1 u = 19.60 ÷ 7 = 2.80
Amount that Paul had at first
= 8 u
= 8 x 2.80
= $22.40
Amount that Winnie had at first
= 22.40 + 30.10
= $52.50
Fraction of money that Winnie had left
= 1 -
47 =
37 Amount that Winnie had at first = 7 p
7 p = 52.50
1 p = 52.50 ÷ 7 = 7.50
Amount that Winnie had left
= 3 p
= 3 x 7.50
= $22.50
Answer(s): $22.50
