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

### Instruction:
Trevor buys three bouquets of carnations. The first included 9 carnations, and the second included 14 carnations. If the average number of carnations in the bouquets is 12, how many carnations were in the third bouquet?

### Response:
 Kuna jumla ya karafuu 36 kwa sababu 9 + 14 + 13 = <<9+14+13=36>>36
Jumla inajumuisha karafuu 13 kwa sababu 3 x 12 = <<3*12=36>>36
Buketi ya tatu ina karafuu <<13=13>>13.
