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

### Instruction:
Meena bakes 5 dozen cookies for the school’s bake sale.  She sells 2 dozen cookies to her biology teacher, Mr. Stone.  Her friend Brock buys 7 cookies, and her friend Katy buys twice as many as Brock.  How many cookies does Meena have left?

### 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.
