| |
Daniel |
Penelope |
| Before |
7 u |
3 p |
| Change |
- 2 u |
- 1 p |
| After |
5 u |
2 p |
Amount that Daniel spent on the pen = 2 u
2 u = 4.60
1 u = 4.60 ÷ 2 = 2.30
Amount that Daniel had at first
= 7 u
= 7 x 2.30
= $16.10
Amount that Penelope had at first
= 16.10 + 41.20
= $57.30
Fraction of money that Penelope had left
= 1 -
13 =
23 Amount that Penelope had at first = 3 p
3 p = 57.30
1 p = 57.30 ÷ 3 = 19.10
Amount that Penelope had left
= 2 p
= 2 x 19.10
= $38.20
Answer(s): $38.20
