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

### 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:
 Mkandarasi anafanya kazi kwa masaa 3*5=<<3*5=15>>15
Hivyo mkandarasi alitoza $150*15=$<<150*15=2250>>2250
Mkaguzi alitoza $2250*.8=$<<2250*.8=1800>>1800 chini
Hivyo mkaguzi alitoza $2250-$1800=$<<2250-1800=450>>450
Hivyo jumla, iligharimu $250+$450+$2250=$<<250+450+2250=2950>>2950
