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

### Instruction:
 Kilo moja ya nyama ya nguruwe inagharimu $6 wakati kilo moja ya kuku inagharimu $2 chini. Gharama ya kuku kilo tatu na kilo moja ya nyama ya nguruwe ni kiasi gani?


### Response:
 Kilo moja ya kuku inagharimu $6 - $2 = $<<6-2=4>>4.
Kuku kilo tatu inagharimu $4 x 3 = $<<3*4=12>>12.
Hivyo, gharama ya kuku kilo tatu na kilo moja ya nyama ya nguruwe ni $12 + $6 = $18.
