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

### Instruction:
John decides to install a ramp in his house.  He needs to get permits which cost $250.  After that, he hires a contractor which costs $150 an hour and the guy works for 3 days at 5 hours per day.  He also pays an inspector 80% less to make sure it is OK.  How much was the total cost?

### Response:
The contractor works for 3*5=<<3*5=15>>15 hours
So the contractor charged 150*15=$<<150*15=2250>>2250
The inspector charged 2250*.8=$1800 less
So the inspector charged 2250-1800=$<<2250-1800=450>>450
The permits charged 250 and the inspector charged 450 and the contractor charged 2250 so the total was 250+450+2250=$<<250+450+2250=2950>>2950
#### 2950
