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

### Instruction:
Lao is farming chickens. He can sell each chicken for $1.50. A bag of chicken feed weighs 20 pounds and costs $2. Each chicken will need 2 pounds of feed from the time it hatches to the time he sells it. If he makes $65 profit from selling chickens, how many did he sell?

### Response:
 Kila begi la chakula linatosha kwa kuku 10 kwa sababu 2 / .2 = <<2/.2=10>>10
Kila kuku linagharimu $0.2 kufuga kwa sababu 2 / 10 = <<2/10=.2>>.2
Kila kuku linatoa faida ya $1.3 kwa sababu 1.5 - .2 = <<1.5-.2=1.3>>1.3
Alivuza kuku 50 kwa sababu 65 / 1.3 = <<65/1.3=50>>50
