35 of his money on a marker which cost $7.50. Anna spent
13 of her money on a blouse. How much had Anna left?
| |
Oliver |
Anna |
| Before |
5 u |
3 p |
| Change |
- 3 u |
- 1 p |
| After |
2 u |
2 p |
Amount that Oliver spent on the marker = 3 u
3 u = 7.50
1 u = 7.50 ÷ 3 = 2.50
Amount that Oliver had at first
= 5 u
= 5 x 2.50
= $12.50
Amount that Anna had at first
= 12.50 + 50.80
= $63.30
Fraction of money that Anna had left
= 1 -
13 =
23 Amount that Anna had at first = 3 p
3 p = 63.30
1 p = 63.30 ÷ 3 = 21.10
Amount that Anna had left
= 2 p
= 2 x 21.10
= $42.20
Answer(s): $42.20
