I need some help with the following problem:

My attempt
(a) I think to reach equilibrium it must satisfy
Is this correct?
(b) When C=160 and R=4000,
So the contribution is that the population of the rabbits reduces by 3876.923 as the result of the interaction?
Could anyone show me how we can calculate how many rabbits did each cat eliminate per year? Any help would be greatly appreciated.

Re: Logistic Model
Yes,

Re: Logistic Model
What definition of "equilibrium" are you using? My understanding of an "equilibrium solution" to a pair of equations is one in which both variables are constant. With C= 160, dC/dt is NOT 0 so I would not call this an equilibrium solution for any value of .

@ HallsofIvy:
Yes, it IS zero.
