Mark |
Fanny |
| Before |
8 u |
3 p |
| Change |
- 7 u |
- 1 p |
| After |
1 u |
2 p |
Amount that Mark spent on the pen = 7 u
7 u = 12.60
1 u = 12.60 ÷ 7 = 1.80
Amount that Mark had at first
= 8 u
= 8 x 1.80
= $14.40
Amount that Fanny had at first
= 14.40 + 77.70
= $92.10
Fraction of money that Fanny had left
= 1 -
13 =
23 Amount that Fanny had at first = 3 p
3 p = 92.10
1 p = 92.10 ÷ 3 = 30.70
Amount that Fanny had left
= 2 p
= 2 x 30.70
= $61.40
Answer(s): $61.40
