George |
Wendy |
| Before |
8 u |
7 p |
| Change |
- 7 u |
- 5 p |
| After |
1 u |
2 p |
Amount that George spent on the stapler = 7 u
7 u = 19.60
1 u = 19.60 ÷ 7 = 2.80
Amount that George had at first
= 8 u
= 8 x 2.80
= $22.40
Amount that Wendy had at first
= 22.40 + 72.80
= $95.20
Fraction of money that Wendy had left
= 1 -
57 =
27 Amount that Wendy had at first = 7 p
7 p = 95.20
1 p = 95.20 ÷ 7 = 13.60
Amount that Wendy had left
= 2 p
= 2 x 13.60
= $27.20
Answer(s): $27.20
