Sean had $49.30 less than Min. He spent
49 of his money on a file which cost $7.20. Min spent
35 of her money on a dress. How much had Min left?
| |
Sean |
Min |
| Before |
9 u |
5 p |
| Change |
- 4 u |
- 3 p |
| After |
5 u |
2 p |
Amount that Sean spent on the file = 4 u
4 u = 7.20
1 u = 7.20 ÷ 4 = 1.80
Amount that Sean had at first
= 9 u
= 9 x 1.80
= $16.20
Amount that Min had at first
= 16.20 + 49.30
= $65.50
Fraction of money that Min had left
= 1 -
35 =
25 Amount that Min had at first = 5 p
5 p = 65.50
1 p = 65.50 ÷ 5 = 13.10
Amount that Min had left
= 2 p
= 2 x 13.10
= $26.20
Answer(s): $26.20
