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

### Instruction:
 James ameamua kuanza kutengeneza kahawa yake mwenyewe. Ananunua mashine ya kahawa kwa $200 na anapata punguzo la $20. Anakadiria kuwa itamgharimu $3 kwa siku kutengeneza kahawa yake. Awali, alikuwa ananunua kahawa 2 kwa $4 kila moja. Itachukua muda gani hadi mashine ilipwe yenyewe?


### Response:
 Alilipa $200-$20=$<<200-20=180>>180 kwa mashine
Awali alikuwa anatumia $4*2=$<<4*2=8>>8 kwa siku
Hivyo anapata akiba ya $8-$3=$<<8-3=5>>5 kwa siku
Itamchukua $180/$5=<<180/5=36>>36 siku kulipia gharama yake.
