Sean |
Linda |
| Before |
9 u |
3 p |
| Change |
- 7 u |
- 1 p |
| After |
2 u |
2 p |
Amount that Sean spent on the marker = 7 u
7 u = 14.70
1 u = 14.70 ÷ 7 = 2.10
Amount that Sean had at first
= 9 u
= 9 x 2.10
= $18.90
Amount that Linda had at first
= 18.90 + 67.20
= $86.10
Fraction of money that Linda had left
= 1 -
13 =
23 Amount that Linda had at first = 3 p
3 p = 86.10
1 p = 86.10 ÷ 3 = 28.70
Amount that Linda had left
= 2 p
= 2 x 28.70
= $57.40
Answer(s): $57.40
