Penelope |
| Before |
3 u |
9 p |
| Change |
- 2 u |
- 5 p |
| After |
1 u |
4 p |
Amount that Reggie spent on the pencil = 2 u
2 u = 4.20
1 u = 4.20 ÷ 2 = 2.10
Amount that Reggie had at first
= 3 u
= 3 x 2.10
= $6.30
Amount that Penelope had at first
= 6.30 + 30.60
= $36.90
Fraction of money that Penelope had left
= 1 -
59 =
49 Amount that Penelope had at first = 9 p
9 p = 36.90

Amount that Penelope had left
= 4 p
= 4 x 4.10
= $16.40
