Archie |
Cindy |
| Before |
3 u |
5 p |
| Change |
- 2 u |
- 3 p |
| After |
1 u |
2 p |
Amount that Archie spent on the notebook = 2 u
2 u = 3.40
1 u = 3.40 ÷ 2 = 1.70
Amount that Archie had at first
= 3 u
= 3 x 1.70
= $5.10
Amount that Cindy had at first
= 5.10 + 74.40
= $79.50
Fraction of money that Cindy had left

= $31.80
