dN/dt = rN (K-N/K ) The logistic equation above is used to describe the rate of change of a population, N, with time, t, Where r is the intrinsic rate of increase and K is the carrying capacity. What is value of per capita growth rate when population size is 200 individuals? ( K= 400, r =.25)

To estimate the number of foxes in an area, a researcher conducted a mark-recapture survey. In the first survey, he caught and marked N number of foxes. In his second survey a week later, he caught 120 foxes of which 90 were unmarked (recaptures). If you are told that the actual number of foxes in this area is 400, what is value of N in this area?
