Liam |
Opal |
| Before |
5 u |
3 p |
| Change |
- 3 u |
- 1 p |
| After |
2 u |
2 p |
Amount that Liam spent on the notebook = 3 u
3 u = 4.50
1 u = 4.50 ÷ 3 = 1.50
Amount that Liam had at first
= 5 u
= 5 x 1.50
= $7.50
Amount that Opal had at first
= 7.50 + 48.60
= $56.10
Fraction of money that Opal had left

13 =
23 Amount that Opal had at first = 3 p
3 p = 56.10
1 p = 56.10 ÷ 3 = 18.70
Amount that Opal had left

= 2 x 18.70
= $37.40
Answer(s): $37.40
