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

### Instruction:
Martin owns a farm with hens. 10 hens do lay 80 eggs in 10 days. Martin decided to buy 15 more hens. How many eggs will all hens lay in 15 days?

### Response:
 Kuku 10 huzalisha mayai 80 katika siku 10.
Hivyo, katika siku 15, kuku 10 watazalisha mayai 80 x 15/10 = <<80*15/10=120>>120.
Kuku 15 watazalisha mayai 15 x 120 = <<15*120=1800>>1800 katika siku 15.
Hivyo, jumla ya mayai yatakayozalishwa na kuku wote katika siku 15 ni 120 + 1800 = <<120+1800=1920>>1920 mayai.
