Below is an instruction that describes a task. Write a response that appropriately completes the request in Thai. Please answer in Thai.

### Instruction:
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?

### Response:
 ช่องถัดไป 100 ช่องมีราคา 100/2 = $<<100/2=50>>50
ดังนั้นราคารวมทั้งหมดคือ 100 + 50 = $<<100+50=150>>150
ดังนั้นเขาจ่าย 150/2 = $<<150/2=75>>75
