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

### Instruction:
Enrico owns a rooster farm, he sells each rooster for $0.50 per kilogram. He was able to sell a 30-kilogram rooster and a 40-kilogram rooster, how much money was he able to earn?

### Response:
 Enrico alikuwa na uwezo wa kuuza kuku wa kilogramu 30 kwa 30 x 0.50 = $<<30*0.50=15>>15.
Na alikuwa na uwezo wa kuuza kuku wa kilogramu 40 kwa 40 x 0.50 = $<<40*0.50=20>>20.
Hivyo, jumla ya pesa aliyopata ni $20 + $15 = $<<20+15=35>>35.
