Pierre |
Elyse |
| Before |
4 u |
7 p |
| Change |
- 3 u |
- 5 p |
| After |
1 u |
2 p |
Amount that Pierre spent on the pen = 3 u
3 u = 7.20
1 u = 7.20 ÷ 3 = 2.40
Amount that Pierre had at first
= 4 u
= 4 x 2.40
= $9.60
Amount that Elyse had at first
= 9.60 + 75.80
= $85.40
Fraction of money that Elyse had left
= 1 -
57 =
27 Amount that Elyse had at first = 7 p
7 p = 85.40
1 p = 85.40 ÷ 7 = 12.20
Amount that Elyse had left
= 2 p
= 2 x 12.20
= $24.40
Answer(s): $24.40
