### Instruction:
To make a shed in his backyard, Tom needs 1000 bricks. He can buy half of the bricks for 50% off of $.50. The other Half he needs to pay full price. How many dollars does Tom spend?

### Response:
Tom spends $.50 on 500 bricks, so he spends $.25 on 250 bricks.
He spends $.50 on the other 500 bricks.
So, Tom spends $.50 + $.50 = $<<.50+.50=1.00>>1.00 on 1000 bricks.
