Vincent |
Risa |
| Before |
7 u |
4 p |
| Change |
- 3 u |
- 1 p |
| After |
4 u |
3 p |
Amount that Vincent spent on the pen = 3 u
3 u = 5.10
1 u = 5.10 ÷ 3 = 1.70
Amount that Vincent had at first
= 7 u
= 7 x 1.70
= $11.90
Amount that Risa had at first
= 11.90 + 35.70
= $47.60
Fraction of money that Risa had left
= 1 -
14 =
34 Amount that Risa had at first = 4 p
4 p = 47.60
1 p = 47.60 ÷ 4 = 11.90
Amount that Risa had left
= 3 p
= 3 x 11.90
= $35.70
Answer(s): $35.70
