Tom |
Joelle |
| Before |
9 u |
3 p |
| Change |
- 4 u |
- 1 p |
| After |
5 u |
2 p |
Amount that Tom spent on the notebook = 4 u
4 u = 7.60
1 u = 7.60 ÷ 4 = 1.90
Amount that Tom had at first
= 9 u
= 9 x 1.90
= $17.10
Amount that Joelle had at first
= 17.10 + 31.80
= $48.90
Fraction of money that Joelle had left

13 =
23 Amount that Joelle had at first = 3 p
3 p = 48.90
1 p = 48.90 ÷ 3 = 16.30
Amount that Joelle had left

= 2 x 16.30
= $32.60
Answer(s): $32.60
