Justin |
Jen |
| Before |
9 u |
3 p |
| Change |
- 4 u |
- 1 p |
| After |
5 u |
2 p |
Amount that Justin spent on the pencil = 4 u
4 u = 5.60
1 u = 5.60 ÷ 4 = 1.40
Amount that Justin had at first
= 9 u
= 9 x 1.40
= $12.60
Amount that Jen had at first
= 12.60 + 21.30
= $33.90
Fraction of money that Jen had left
= 1 -
13 =
23 Amount that Jen had at first = 3 p
3 p = 33.90
1 p = 33.90 ÷ 3 = 11.30
Amount that Jen had left
= 2 p
= 2 x 11.30
= $22.60
Answer(s): $22.60
