Olivia |
| Before |
3 u |
7 p |
| Change |
- 2 u |
- 4 p |
| After |
1 u |
3 p |
Amount that Paul spent on the stapler = 2 u
2 u = 2.20
1 u = 2.20 ÷ 2 = 1.10
Amount that Paul had at first
= 3 u
= 3 x 1.10
= $3.30
Amount that Olivia had at first
= 3.30 + 42.90
= $46.20
Fraction of money that Olivia had left
