23 of his money on a file which cost $2.40. Sarah spent
47 of her money on a skirt. How much had Sarah left?
| |
Reggie |
Sarah |
| Before |
3 u |
7 p |
| Change |
- 2 u |
- 4 p |
| After |
1 u |
3 p |
Amount that Reggie spent on the file = 2 u
2 u = 2.40
1 u = 2.40 ÷ 2 = 1.20
Amount that Reggie had at first
= 3 u
= 3 x 1.20
= $3.60
Amount that Sarah had at first
= 3.60 + 20.20
= $23.80
Fraction of money that Sarah had left
= 1 -
47 =
37 Amount that Sarah had at first = 7 p
7 p = 23.80
1 p = 23.80 ÷ 7 = 3.40
Amount that Sarah had left
= 3 p
= 3 x 3.40
= $10.20
Answer(s): $10.20
