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

### Instruction:
 Marco anamiliki gari la barafu. Keki zake za barafu ni $5 kila moja. Ikiwa gharama zake ni 80% ya mauzo yote ya siku hiyo, anahitaji kuuza keki ngapi za barafu ili kupata faida ya $200 kwa siku?


### Response:
 Gharama zake ni 80/100=<<80/100=0.8>>0.8
Faida yake ingekuwa 20/100=<<20/100=0.2>>0.2
Mauzo yote ya siku hiyo ni $200 x 100/20= $<<200*100/20=1000>>1000
Jumla ya keki za barafu anazouza ni $1000 / $5= <<1000/5=200>>200
