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

### Instruction:
 Mama wa Miggy alileta nyumbani mifuko 3 ya kofia za kuzaliwa. Kila mfuko una kofia 15. Miggy kwa bahati mbaya alirarua kofia 5. Wakati wa sherehe, kofia 25 tu zilitumika. Kofia ngapi zilitumika?


### Response:
 Kulikuwa na kofia 3 x 15 = <<3*15=45>>45 jumla.
Miggy alirarua kofia 5.
Hivyo, zilisalia kofia 45 - 5 = <<45-5=40>>40.
Kofia 25 zilitumika tu.
Hivyo, kofia 40 - 25 = <<40-25=15>>15 zilikuwa hazijatumika.
