Pierre |
Joelle |
| Before |
4 u |
3 p |
| Change |
- 3 u |
- 1 p |
| After |
1 u |
2 p |
Amount that Pierre spent on the stapler = 3 u
3 u = 8.40
1 u = 8.40 ÷ 3 = 2.80
Amount that Pierre had at first
= 4 u
= 4 x 2.80
= $11.20
Amount that Joelle had at first
= 11.20 + 74.60
= $85.80
Fraction of money that Joelle had left
= 1 -
13 =
23 Amount that Joelle had at first = 3 p
3 p = 85.80
1 p = 85.80 ÷ 3 = 28.60
Amount that Joelle had left
= 2 p
= 2 x 28.60
= $57.20
Answer(s): $57.20
