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

### Instruction:
The price of candy bars is twice the cost of caramel, and the cost of cotton candy is half the price of 4 candy bars. If the price of 1 caramel is $3, how much do 6 candy bars, 3 caramel, and 1 cotton candy cost together?

### Response:
 Mikate ya pipi kila moja inagharimu $3 * 2 = $<<3*2=6>>6.
Pamba ya sukari kila moja inagharimu 1/2 * (4 * $6) = $12.
Mikate 6 ya pipi inagharimu 6 mikate * $6/kate = $<<6*6=36>>36.
Karameli 3 inagharimu 3 karameli * $3/karameli = $<<3*3=9>>9.
Jumla ya pipi zote ni $36 + $9 + $12 = $<<36+9+12=57>>57.
