John |
Linda |
| Before |
7 u |
3 p |
| Change |
- 2 u |
- 1 p |
| After |
5 u |
2 p |
Amount that John spent on the pen = 2 u
2 u = 2.80
1 u = 2.80 ÷ 2 = 1.40
Amount that John had at first
= 7 u
= 7 x 1.40
= $9.80
Amount that Linda had at first
= 9.80 + 23.50
= $33.30
Fraction of money that Linda had left
= 1 -
13 =
23 Amount that Linda had at first = 3 p
3 p = 33.30
1 p = 33.30 ÷ 3 = 11.10
Amount that Linda had left
= 2 p
= 2 x 11.10
= $22.20
Answer(s): $22.20
