A certain species has an instantaneous growth rate of 27 percent per year when not affected by crowding. Experimentally, for each 1000 of the species the birth rate drops by 12 per 1000 per year, and the death rate increases by 50 per 1000 per year. Determine the parameters of a logistic equation which models this species. What is the expected nonzero equilibrium population
