David |
Gabby |
| Before |
8 u |
7 p |
| Change |
- 5 u |
- 5 p |
| After |
3 u |
2 p |
Amount that David spent on the marker = 5 u
5 u = 9.50
1 u = 9.50 ÷ 5 = 1.90
Amount that David had at first
= 8 u
= 8 x 1.90
= $15.20
Amount that Gabby had at first
= 15.20 + 73.70
= $88.90
Fraction of money that Gabby had left
= 1 -
57 =
27 Amount that Gabby had at first = 7 p
7 p = 88.90
1 p = 88.90 ÷ 7 = 12.70
Amount that Gabby had left
= 2 p
= 2 x 12.70
= $25.40
Answer(s): $25.40
