Albert |
Kathy |
| Before |
9 u |
5 p |
| Change |
- 4 u |
- 1 p |
| After |
5 u |
4 p |
Amount that Albert spent on the pen = 4 u
4 u = 6.80
1 u = 6.80 ÷ 4 = 1.70
Amount that Albert had at first
= 9 u
= 9 x 1.70
= $15.30
Amount that Kathy had at first
= 15.30 + 73.20
= $88.50
Fraction of money that Kathy had left
= 1 -
15 =
45 Amount that Kathy had at first = 5 p
5 p = 88.50
1 p = 88.50 ÷ 5 = 17.70
Amount that Kathy had left
= 4 p
= 4 x 17.70
= $70.80
Answer(s): $70.80
