23 of his money on a stapler which cost $5.40. Lucy spent
14 of her money on a blouse. How much had Lucy left?
| |
Ivan |
Lucy |
| Before |
3 u |
4 p |
| Change |
- 2 u |
- 1 p |
| After |
1 u |
3 p |
Amount that Ivan spent on the stapler = 2 u
2 u = 5.40
1 u = 5.40 ÷ 2 = 2.70
Amount that Ivan had at first
= 3 u
= 3 x 2.70
= $8.10
Amount that Lucy had at first
= 8.10 + 27.50
= $35.60
Fraction of money that Lucy had left
= 1 -
14 =
34 Amount that Lucy had at first = 4 p
4 p = 35.60
1 p = 35.60 ÷ 4 = 8.90
Amount that Lucy had left
= 3 p
= 3 x 8.90
= $26.70
Answer(s): $26.70
