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

### Instruction:
A cookfire burns three logs every hour. It was built with six logs to start. If it gets two more logs added to it at the end of every hour, how many logs will be left after 3 hours?

### Response:
 Baada ya masaa matatu, itakuwa imechoma magogo 3 * 3 = <<3*3=9>>9.
Baada ya masaa matatu, itakuwa imeongeza magogo 6 + 2 * 3 = <<6+2*3=12>>12.
Baada ya masaa matatu, itakuwa imebakiwa na magogo 12 - 9 = <<12-9=3>>3.
