Jack |
Eva |
| Before |
7 u |
9 p |
| Change |
- 3 u |
- 2 p |
| After |
4 u |
7 p |
Amount that Jack spent on the stapler = 3 u
3 u = 6.90
1 u = 6.90 ÷ 3 = 2.30
Amount that Jack had at first
= 7 u
= 7 x 2.30
= $16.10
Amount that Eva had at first
= 16.10 + 34.30
= $50.40
Fraction of money that Eva had left
= 1 -
29 =
79 Amount that Eva had at first = 9 p
9 p = 50.40
1 p = 50.40 ÷ 9 = 5.60
Amount that Eva had left
= 7 p
= 7 x 5.60
= $39.20
Answer(s): $39.20
