| |
David |
Marion |
| Before |
7 u |
3 p |
| Change |
- 4 u |
- 1 p |
| After |
3 u |
2 p |
Amount that David spent on the pen = 4 u
4 u = 10.40
1 u = 10.40 ÷ 4 = 2.60
Amount that David had at first
= 7 u
= 7 x 2.60
= $18.20
Amount that Marion had at first
= 18.20 + 58.60
= $76.80
Fraction of money that Marion had left
= 1 -
13 =
23 Amount that Marion had at first = 3 p
3 p = 76.80
1 p = 76.80 ÷ 3 = 25.60
Amount that Marion had left
= 2 p
= 2 x 25.60
= $51.20
Answer(s): $51.20
