Ivan |
Yoko |
| Before |
7 u |
9 p |
| Change |
- 5 u |
- 5 p |
| After |
2 u |
4 p |
Amount that Ivan spent on the stapler = 5 u
5 u = 5.50
1 u = 5.50 ÷ 5 = 1.10
Amount that Ivan had at first
= 7 u
= 7 x 1.10
= $7.70
Amount that Yoko had at first
= 7.70 + 56.20
= $63.90
Fraction of money that Yoko had left
= 1 -
59 =
49 Amount that Yoko had at first = 9 p
9 p = 63.90
1 p = 63.90 ÷ 9 = 7.10
Amount that Yoko had left

= 4 x 7.10
= $28.40
Answer(s): $28.40
