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

### Instruction:
A farmer owns a hog that recently gave birth to 6 piglets.  If the farmer raises the piglets until they are fully grown, he can sell the fully grown pig for $300.  Each piglet must grow for at least 12 months before it is large enough to be sold. It costs the farmer $10 per month to feed each animal until it is sold.  If the farmer sells 3 pigs after 12 months, and the remaining 3 pigs after 16 months, how much profit did he earn in total (after deducting the cost of food)?

### Response:
 Nguruwe 3 ambao wanauzwa baada ya miezi 12 wataigharimu mkulima 12*10*3=<<12*10*3=360>>360 dola kwa gharama ya chakula.
Nguruwe 3 ambao wanauzwa baada ya miezi 16 wataigharimu mkulima 16*10*3=<<16*10*3=480>>480 dola kwa gharama ya chakula.
Hivyo, gharama jumla ya chakula kuwalea watoto 6 wa nguruwe ilikuwa 360 + 480= <<360+480=840>>840 dola.
Kisha, mapato kutokana na kuuza nguruwe waliokua kabisa ni 6 * 300=<<6*300=1800>>1800 dola.
Hivyo, faida jumla ilikuwa 1800- 840=<<1800-840=960>>960 dola.
