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

### Instruction:
 Joshua alinunua machungwa 25 kwa $12.50. Ikiwa anauza kila kimoja kwa 60c, atapata faida kiasi gani kwa kila chungwa kwa senti?


### Response:
 Alinunua machungwa 25 kwa 12.50 ambayo ni 12.50/25 = 50 senti kila kimoja.
Ikiwa anauza kila chungwa kwa 60 senti, atapata faida ya 60 - 50 = <<60-50=10>>10 senti kwa kila kimoja.
