I'm working on my environmental engineering homework and I'm not sure how to solve this problem.
Original Info: A farmer owns 20 chickens. After one year he has 100 chickens due to the reproduction of the original 20 chickens.
I solved that the growth rate is 161% and the doubling time is 0.43 years.
THE QUESTION: If the farmer wants to sell 1000 chickens per month, how many chickens must he maintain on his farm at all times to sustain his chicken-selling business?
I think I provided all the information necessary but if I left anything out please let me know!
Thank you for your response!
