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

### Instruction:
The cost of Joe's new HVAC system is $20,000.  It includes 2 conditioning zones, each with 5 vents.  In dollars, what is the cost of the system per vent?

### Response:
Two zones with 5 vents per zone is 2*5 = <<2*5=10>>10 vents.
Thus, the $20,000 system costs $20,000/10 = $<<20000/10=2000>>2,000 per vent.
