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

### Instruction:
 Jett alinunua ng'ombe kutoka sokoni kwa $600 na akampeleka shambani kwake. Alitumia $20 kila siku kununua chakula. Pia alitumia $500 kumchania na kumwondoa minyoo ng'ombe. Ikiwa aliouza ng'ombe kwa $2500 baada ya siku 40, hesabu faida aliyoipata kwa kumrudishia ng'ombe sokoni.


### Response:
 Gharama jumla ya chakula ambacho ng'ombe alikula kwa siku arobaini ni 40*$20 = $<<40*20=800>>800
Kulisha na kudumisha afya ya ng'ombe, gharama jumla ambayo Jett alitumia ni $500+$800 = $<<500+800=1300>>1300
Kwa gharama hizo, Jett alitumia $1300+$600 = $<<1300+600=1900>>1900 kwa ng'ombe.
Ikiwa aliouza ng'ombe kwa $2500, Jett alipata faida ya $2500-$1900 = $<<2500-1900=600>>600
