Luis had $30.20 less than Jean. He spent
49 of his money on a file which cost $6.80. Jean spent
25 of her money on a sweater. How much had Jean left?
| |
Luis |
Jean |
| Before |
9 u |
5 p |
| Change |
- 4 u |
- 2 p |
| After |
5 u |
3 p |
Amount that Luis spent on the file = 4 u
4 u = 6.80
1 u = 6.80 ÷ 4 = 1.70
Amount that Luis had at first
= 9 u
= 9 x 1.70
= $15.30
Amount that Jean had at first
= 15.30 + 30.20
= $45.50
Fraction of money that Jean had left
= 1 -
25 =
35 Amount that Jean had at first = 5 p
5 p = 45.50
1 p = 45.50 ÷ 5 = 9.10
Amount that Jean had left
= 3 p
= 3 x 9.10
= $27.30
Answer(s): $27.30
