James gets a cable program.  The first 100 channels cost $100 and the next 100 channels cost half that much.  He splits it evenly with his roommate.  How much did he pay?
The next 100 channels cost 100/2=$<<100/2=50>>50
So the total cost is 100+50=$<<100+50=150>>150
So he pays 150/2=$<<150/2=75>>75
#### 75
