Luis |
Penelope |
| Before |
7 u |
5 p |
| Change |
- 2 u |
- 2 p |
| After |
5 u |
3 p |
Amount that Luis spent on the pencil = 2 u
2 u = 3.40
1 u = 3.40 ÷ 2 = 1.70
Amount that Luis had at first
= 7 u
= 7 x 1.70
= $11.90
Amount that Penelope had at first
= 11.90 + 40.60
= $52.50
Fraction of money that Penelope had left
= 1 -
25 =
35 Amount that Penelope had at first = 5 p
5 p = 52.50
1 p = 52.50 ÷ 5 = 10.50
Amount that Penelope had left
= 3 p
= 3 x 10.50
= $31.50
Answer(s): $31.50
