Ahmad |
Jean |
| Before |
4 u |
7 p |
| Change |
- 3 u |
- 3 p |
| After |
1 u |
4 p |
Amount that Ahmad spent on the marker = 3 u
3 u = 4.20
1 u = 4.20 ÷ 3 = 1.40
Amount that Ahmad had at first
= 4 u
= 4 x 1.40
= $5.60
Amount that Jean had at first
= 5.60 + 31.50
= $37.10
Fraction of money that Jean had left
= 1 -
37 =
47 Amount that Jean had at first = 7 p
7 p = 37.10
1 p = 37.10 ÷ 7 = 5.30
Amount that Jean had left
= 4 p
= 4 x 5.30
= $21.20
Answer(s): $21.20
