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

### Instruction:
 Meena anapika mikate 5 kwa shule ya kuuza. Anauza mikate 2 kwa mwalimu wake wa biolojia, Bwana Stone. Rafiki yake Brock ananunua mikate 7, na rafiki yake Katy ananunua mara mbili ya Brock. Meena anabakiwa na mikate mingapi?


### Response:
 Meena anapika jumla ya mikate 5 x 12 = <<5*12=60>>60.
Bwana Stone ananunua mikate 2 x 12 = <<2*12=24>>24.
Brock ananunua mikate 7, hivyo Katy ananunua mikate 2 x 7 = 14.
Meena anauza jumla ya mikate 24 + 7 + 14 = <<24+7+14=45>>45.
Anabakiwa na mikate 60 - 45 = <<60-45=15>>15.
