Peter |
Lynn |
| Before |
8 u |
5 p |
| Change |
- 3 u |
- 1 p |
| After |
5 u |
4 p |
Amount that Peter spent on the notebook = 3 u
3 u = 4.20
1 u = 4.20 ÷ 3 = 1.40
Amount that Peter had at first
= 8 u
= 8 x 1.40
= $11.20
Amount that Lynn had at first
= 11.20 + 58.30
= $69.50
Fraction of money that Lynn had left
= 1 -
15 =
45 Amount that Lynn had at first = 5 p
5 p = 69.50

Amount that Lynn had left

= 4 x 13.90
= $55.60
Answer(s): $55.60
