| Before |
8 u |
3 p |
| Change |
- 7 u |
- 1 p |
| After |
1 u |
2 p |
Amount that Albert spent on the pencil = 7 u
7 u = 7.70
1 u = 7.70 ÷ 7 = 1.10
Amount that Albert had at first
= 8 u
= 8 x 1.10
= $8.80
Amount that Raeann had at first
= 8.80 + 77.30
= $86.10
Fraction of money that Raeann had left
= 1 -
13 =
23 Amount that Raeann had at first = 3 p
3 p = 86.10
1 p = 86.10 ÷ 3 = 28.70
Amount that Raeann had left
= 2 p
= 2 x 28.70
= $57.40
Answer(s): $57.40
