Oscar had $30.30 less than Abi. He spent
59 of his money on a stapler which cost $8.50. Abi spent
14 of her money on a vest. How much had Abi left?
| |
Oscar |
Abi |
| Before |
9 u |
4 p |
| Change |
- 5 u |
- 1 p |
| After |
4 u |
3 p |
Amount that Oscar spent on the stapler = 5 u
5 u = 8.50
1 u = 8.50 ÷ 5 = 1.70
Amount that Oscar had at first
= 9 u
= 9 x 1.70
= $15.30
Amount that Abi had at first
= 15.30 + 30.30
= $45.60
Fraction of money that Abi had left
= 1 -
14 =
34 Amount that Abi had at first = 4 p
4 p = 45.60
1 p = 45.60 ÷ 4 = 11.40
Amount that Abi had left
= 3 p
= 3 x 11.40
= $34.20
Answer(s): $34.20
