Zeph |
Betty |
| Before |
5 u |
9 p |
| Change |
- 3 u |
- 2 p |
| After |
2 u |
7 p |
Amount that Zeph spent on the pen = 3 u
3 u = 5.70
1 u = 5.70 ÷ 3 = 1.90
Amount that Zeph had at first
= 5 u
= 5 x 1.90
= $9.50
Amount that Betty had at first
= 9.50 + 75.10
= $84.60
Fraction of money that Betty had left
= 1 -
29 =
79 Amount that Betty had at first = 9 p
9 p = 84.60
1 p = 84.60 ÷ 9 = 9.40
Amount that Betty had left
= 7 p
= 7 x 9.40
= $65.80
Answer(s): $65.80
