Ben |
Roshel |
| Before |
8 u |
7 p |
| Change |
- 5 u |
- 4 p |
| After |
3 u |
3 p |
Amount that Ben spent on the pencil = 5 u
5 u = 11.50
1 u = 11.50 ÷ 5 = 2.30
Amount that Ben had at first
= 8 u
= 8 x 2.30
= $18.40
Amount that Roshel had at first
= 18.40 + 38.30
= $56.70
Fraction of money that Roshel had left
= 1 -
47 =
37 Amount that Roshel had at first = 7 p
7 p = 56.70
1 p = 56.70 ÷ 7 = 8.10
Amount that Roshel had left

= 3 x 8.10
= $24.30
Answer(s): $24.30
