Peter |
Zoe |
| Before |
8 u |
3 p |
| Change |
- 3 u |
- 1 p |
| After |
5 u |
2 p |
Amount that Peter spent on the notebook = 3 u
3 u = 8.10
1 u = 8.10 ÷ 3 = 2.70
Amount that Peter had at first
= 8 u
= 8 x 2.70
= $21.60
Amount that Zoe had at first
= 21.60 + 64.80
= $86.40
Fraction of money that Zoe had left
