Ben |
Lynn |
| Before |
9 u |
3 p |
| Change |
- 5 u |
- 1 p |
| After |
4 u |
2 p |
Amount that Ben spent on the notebook = 5 u
5 u = 8.50
1 u = 8.50 ÷ 5 = 1.70
Amount that Ben had at first
= 9 u
= 9 x 1.70
= $15.30
Amount that Lynn had at first
= 15.30 + 45.30
= $60.60
Fraction of money that Lynn had left
= 1 -
13 =
23 Amount that Lynn had at first = 3 p
3 p = 60.60
1 p = 60.60 ÷ 3 = 20.20
Amount that Lynn had left
= 2 p
= 2 x 20.20
= $40.40
Answer(s): $40.40
