Cole |
Jean |
| Before |
5 u |
7 p |
| Change |
- 2 u |
- 3 p |
| After |
3 u |
4 p |
Amount that Cole spent on the file = 2 u
2 u = 2.60
1 u = 2.60 ÷ 2 = 1.30
Amount that Cole had at first
= 5 u
= 5 x 1.30
= $6.50
Amount that Jean had at first
= 6.50 + 22.90
= $29.40
Fraction of money that Jean had left
= 1 -
37 =
47 Amount that Jean had at first = 7 p
7 p = 29.40
1 p = 29.40 ÷ 7 = 4.20
Amount that Jean had left
= 4 p
= 4 x 4.20
= $16.80
Answer(s): $16.80
