Ethan |
Xuan |
| Before |
4 u |
5 p |
| Change |
- 3 u |
- 2 p |
| After |
1 u |
3 p |
Amount that Ethan spent on the pencil = 3 u
3 u = 6.60
1 u = 6.60 ÷ 3 = 2.20
Amount that Ethan had at first
= 4 u
= 4 x 2.20
= $8.80
Amount that Xuan had at first
= 8.80 + 42.70
= $51.50
Fraction of money that Xuan had left

25 =
35 Amount that Xuan had at first = 5 p
5 p = 51.50

= 3 x 10.30
= $30.90
Answer(s): $30.90
