Tom |
Erika |
| Before |
3 u |
9 p |
| Change |
- 2 u |
- 5 p |
| After |
1 u |
4 p |
Amount that Tom spent on the pencil = 2 u
2 u = 4.40
1 u = 4.40 ÷ 2 = 2.20
Amount that Tom had at first
= 3 u
= 3 x 2.20
= $6.60
Amount that Erika had at first
= 6.60 + 44.70
= $51.30
Fraction of money that Erika had left
= 1 -
59 =
49 Amount that Erika had at first = 9 p
9 p = 51.30
1 p = 51.30 ÷ 9 = 5.70
Amount that Erika had left
= 4 p
= 4 x 5.70
= $22.80
Answer(s): $22.80
