Luke |
Lucy |
| Before |
3 u |
9 p |
| Change |
- 2 u |
- 4 p |
| After |
1 u |
5 p |
Amount that Luke spent on the stapler = 2 u
2 u = 2.40
1 u = 2.40 ÷ 2 = 1.20
Amount that Luke had at first
= 3 u
= 3 x 1.20
= $3.60
Amount that Lucy had at first
= 3.60 + 65.70
= $69.30
Fraction of money that Lucy had left
= 1 -
49 =
59 Amount that Lucy had at first = 9 p
9 p = 69.30
1 p = 69.30 ÷ 9 = 7.70
Amount that Lucy had left
= 5 p
= 5 x 7.70
= $38.50
Answer(s): $38.50
