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

### Instruction:
There are 50 goldfish in the pond. Each goldfish eats 1.5 ounces of food per day. 20% of the goldfish need to eat special food that costs $3 an ounce. How much does it cost to feed these fish?

### Response:
 Asilimia 20 ya samaki wanahitaji chakula maalum hivyo ni .20*50 = <<20*.01*50=10>>10 samaki
Samaki hawa hula unga wa 10*1.5 = <<10*1.5=15>>15 kwa siku
Chakula hiki kinagharimu $3*16 = $<<3*16=48>>48 kwa pauni
Hivyo kinagharimu $48/16 = $<<48/16=3>>3 kwa unsi
Hivyo kinagharimu 15*3 = $<<15*3=45>>45 kuwalisha samaki hawa
