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

### Instruction:
 John anapata bwawa lake kusafishwa kila baada ya siku 3. Gharama ni $150 kila mara na yeye humpa kijana bahshishi ya 10% kila mara anapokuja kusafisha. Kisha mara mbili kwa mwezi anahitaji kutumia kemikali za $200. Gharama ya bwawa lake ni kiasi gani kwa mwezi?


### Response:
 Anapata bwawa lake kusafishwa mara 10 kwa mwezi
Kila mara anapopata kusafishwa humpa bahshishi ya 150*.1=$<<150*.1=15>>15
Hivyo analipa 150+15=$<<150+15=165>>165
Hivyo analipa 165*10=$<<165*10=1650>>1650 kwa mwezi kwa usafi
Kemikali zinagharimu 200*2=$<<200*2=400>>400
Hivyo jumla, analipa 1650+400=$<<1650+400=2050>>2050
