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

### Instruction:
 James ananunua chupa ya pilipili kali. Kila huduma ni onsi 0.5. Anatumia huduma 3 kila siku. Ikiwa chombo kina onsi 2 chini ya robo 1, itadumu kwa siku ngapi?


### Response:
 Robo ni onsi 32 hivyo chupa hii ni onsi 32-2=<<32-2=30>>30
James anatumia onsi 3*.5=<<3*.5=1.5>>1.5 kwa siku
Hivyo itadumu kwa siku 30/1.5=<<30/1.5=20>>20.
