Cindy |
| Before |
7 u |
4 p |
| Change |
- 6 u |
- 1 p |
| After |
1 u |
3 p |
Amount that Flynn spent on the file = 6 u
6 u = 7.80
1 u = 7.80 ÷ 6 = 1.30
Amount that Flynn had at first
= 7 u
= 7 x 1.30
= $9.10
Amount that Cindy had at first
= 9.10 + 31.30
= $40.40
Fraction of money that Cindy had left
= 1 -
14 =
34 Amount that Cindy had at first = 4 p
4 p = 40.40
1 p = 40.40 ÷ 4 = 10.10
Amount that Cindy had left
= 3 p
= 3 x 10.10
= $30.30
Answer(s): $30.30
