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

### Instruction:
 Bob ananunua mikate 12 kwa siku kwa $0.75 kila mmoja na kisha anawauza kwa $1.5 kila mmoja. Anapata faida kiasi gani kwa wiki?


### Response:
 Ananunua kwa $12 * 0.75 = $<<12*.75=9>>9
Anawauza kwa $1.5 * 12 = $<<1.5*12=18>>18
Hivyo anapata $18 - $9 = $<<18-9=9>>9 kwa siku
Hivyo anapata $9 * 7 = $<<9*7=63>>63 kwa wiki
