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

### Instruction:
 Kwa kila duzini ya maua inayonunuliwa, mteja hupata maua 2 bure. Ikiwa Maria anataka kununua duzini 3 za maua, atakuwa na maua mangapi jumla?


### Response:
 Maria ana maua 6 bure kutokana na kununua duzini 3 za maua.
Kwa kuwa kila duzini ina maua 12, basi Maria amenunua maua 3 x 12 = 36.
Hivyo, idadi ya jumla ya maua ambayo Maria anayo ni 36 + 6 = 42.
