Will |
Erika |
| Before |
5 u |
7 p |
| Change |
- 3 u |
- 3 p |
| After |
2 u |
4 p |
Amount that Will spent on the stapler = 3 u
3 u = 8.10
1 u = 8.10 ÷ 3 = 2.70
Amount that Will had at first
= 5 u
= 5 x 2.70
= $13.50
Amount that Erika had at first
= 13.50 + 29.20
= $42.70
Fraction of money that Erika had left
= 1 -
37 =
47 Amount that Erika had at first = 7 p
7 p = 42.70

Amount that Erika had left

= 4 x 6.10
= $24.40
Answer(s): $24.40
