Glen |
Lucy |
| Before |
7 u |
4 p |
| Change |
- 3 u |
- 1 p |
| After |
4 u |
3 p |
Amount that Glen spent on the stapler = 3 u
3 u = 7.80
1 u = 7.80 ÷ 3 = 2.60
Amount that Glen had at first
= 7 u
= 7 x 2.60
= $18.20
Amount that Lucy had at first
= 18.20 + 36.60
= $54.80
Fraction of money that Lucy had left
= 1 -
14 =
34 Amount that Lucy had at first = 4 p
4 p = 54.80
1 p = 54.80 ÷ 4 = 13.70
Amount that Lucy had left
= 3 p
= 3 x 13.70
= $41.10
Answer(s): $41.10
