Hello everyone! Tried to solve this but I seem to get the wrong answer, any help? It is estimated that the annual proportionate growth rate R(P) of a particular animal population is 1.4 when the population size P is 70, and 1.2 when P is 210. Assuming that the behaviour of the population satisfies the logistic model, choose the TWO options that give the approximate proportionate growth rate for low populations, r, and the approximate equilibrium population, E. I got r = 1.6 E = 0.125
