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

### Instruction:
Denver uses 7 pieces of wood for each birdhouse and he pays $1.50 for each piece of wood. If he makes a $5.50 profit per birdhouse, how much will Denver charge to Danny for buying two birdhouses?

### Response:
 Gharama ya kutengeneza nyumba moja ya ndege ni $1.50 x 7 = $<<1.5*7=10.50>>10.50.
Hivyo bei ya kuuza ya nyumba moja ya ndege ni $10.50 + $5.50 = $16.
Hivyo, Denver atamtoza Danny $16 x 2 = $32 kwa nyumba mbili za ndege.
