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

### Instruction:
Sylvie is feeding her turtles. Each turtle needs 1 ounce of food per 1/2 pound of body weight. She has 30 pounds of turtles. Each jar of food contains 15 ounces and costs $2.  How much does it cost to feed the turtles?

### Response:
 Anahitaji unga wa chakula wa unsi 60 kwa sababu 30 / .5 = <<30/.5=60>>60
Anahitaji chupa 4 za chakula kwa sababu 60 / 15 = <<60/15=4>>4
Itagharimu $8 kuwalisha kobe kwa sababu 4 x 2 = 8
