Pierre |
Zara |
| Before |
9 u |
5 p |
| Change |
- 2 u |
- 2 p |
| After |
7 u |
3 p |
Amount that Pierre spent on the stapler = 2 u
2 u = 4.80
1 u = 4.80 ÷ 2 = 2.40
Amount that Pierre had at first
= 9 u
= 9 x 2.40
= $21.60
Amount that Zara had at first
= 21.60 + 59.90
= $81.50
Fraction of money that Zara had left
= 1 -
25 =
35 Amount that Zara had at first = 5 p
5 p = 81.50
1 p = 81.50 ÷ 5 = 16.30
Amount that Zara had left
= 3 p
= 3 x 16.30
= $48.90
Answer(s): $48.90
