George |
Betty |
| Before |
5 u |
4 p |
| Change |
- 3 u |
- 1 p |
| After |
2 u |
3 p |
Amount that George spent on the notebook = 3 u
3 u = 6.30
1 u = 6.30 ÷ 3 = 2.10
Amount that George had at first
= 5 u
= 5 x 2.10
= $10.50
Amount that Betty had at first
= 10.50 + 46.70
= $57.20
Fraction of money that Betty had left
= 1 -
14 =
34 Amount that Betty had at first = 4 p
4 p = 57.20

= 3 x 14.30
= $42.90
Answer(s): $42.90
