Oscar |
Barbara |
| Before |
8 u |
7 p |
| Change |
- 5 u |
- 5 p |
| After |
3 u |
2 p |
Amount that Oscar spent on the marker = 5 u
5 u = 6.50
1 u = 6.50 ÷ 5 = 1.30
Amount that Oscar had at first
= 8 u
= 8 x 1.30
= $10.40
Amount that Barbara had at first
= 10.40 + 33.70
= $44.10
Fraction of money that Barbara had left
= 1 -
57 =
27 Amount that Barbara had at first = 7 p
7 p = 44.10
1 p = 44.10 ÷ 7 = 6.30
Amount that Barbara had left
= 2 p
= 2 x 6.30
= $12.60
Answer(s): $12.60
