Carl had $51.40 less than Opal. He spent
47 of his money on a stapler which cost $10.40. Opal spent
13 of her money on a jacket. How much had Opal left?
| |
Carl |
Opal |
| Before |
7 u |
3 p |
| Change |
- 4 u |
- 1 p |
| After |
3 u |
2 p |
Amount that Carl spent on the stapler = 4 u
4 u = 10.40
1 u = 10.40 ÷ 4 = 2.60
Amount that Carl had at first
= 7 u
= 7 x 2.60
= $18.20
Amount that Opal had at first
= 18.20 + 51.40
= $69.60
Fraction of money that Opal had left
= 1 -
13 =
23 Amount that Opal had at first = 3 p
3 p = 69.60
1 p = 69.60 ÷ 3 = 23.20
Amount that Opal had left
= 2 p
= 2 x 23.20
= $46.40
Answer(s): $46.40
