Lee bought some pastries. He bought some scones with $8.80 more than half his money. He then bought some croissants with $3.90 less than half of his remaining money. He then had $9.30 left. How much did he pay for the scones?
| Scones |
Remaining amount |
| 1 u + $8.80 |
1 u - $8.80 |

1 p - $3.90 |
1 p + $3.90 |

|
$9.30 |
Working backwards.
Amount that Lee had left = 1 p + 3.90
1 p + 3.90 = 9.30
1 p = 9.30 - 3.90 = 5.40
Remaining amount after he bought some scones
= 2 p
= 2 x 5.40
= $10.80
Remaining amount after he bought some scones = 1 u - 8.80
1 u - 8.80 = 10.80
1 u = 10.80 + 8.80
1 u = 19.60
Amount that Lee spent on some scones
= 1 u + 8.80
= 19.60 + 8.80
= $28.40
Answer(s): $28.40
