Zeph |
Sarah |
| Before |
3 u |
7 p |
| Change |
- 2 u |
- 4 p |
| After |
1 u |
3 p |
Amount that Zeph spent on the file = 2 u
2 u = 4.60
1 u = 4.60 ÷ 2 = 2.30
Amount that Zeph had at first
= 3 u
= 3 x 2.30
= $6.90
Amount that Sarah had at first
= 6.90 + 26.70
= $33.60
Fraction of money that Sarah had left
= 1 -
47 =
37 Amount that Sarah had at first = 7 p
7 p = 33.60
1 p = 33.60 ÷ 7 = 4.80
Amount that Sarah had left
= 3 p
= 3 x 4.80
= $14.40
Answer(s): $14.40
