Peter |
Pamela |
| Before |
5 u |
3 p |
| Change |
- 2 u |
- 1 p |
| After |
3 u |
2 p |
Amount that Peter spent on the file = 2 u
2 u = 3.80
1 u = 3.80 ÷ 2 = 1.90
Amount that Peter had at first
= 5 u
= 5 x 1.90
= $9.50
Amount that Pamela had at first
= 9.50 + 21.40
= $30.90
Fraction of money that Pamela had left
= 1 -
13 =
23 Amount that Pamela had at first = 3 p
3 p = 30.90
1 p = 30.90 ÷ 3 = 10.30
Amount that Pamela had left
= 2 p
= 2 x 10.30
= $20.60
Answer(s): $20.60
