I especially need help with part e

Given the equations COP-S) (1) fD where I immigration P -total number of species in the mainland pool, given as 500 species S species richness of the island D distance of the island from the mainland, given as 200m c colonization probability (probability that a given species will make it to island) given as 0.10 1- a scaling factor for distance, given as 0.01 and as (2) Am where E extinction rate S species richness of the island A area of the island, given as 100 m q extinction probability for a given species, given as 0.20 m a power scaling factor, given as 0.25 Calculate the immigration and extinction rates when the fraction of species found on the island is a) 0.3 of the mainlands total number of species b) 0.5 of the mainlands total number of species c) 0.7 of the mainlands total number of species d) 1.0 of the mainlands total number of species e) What is the equilibrium number of species (S*) for this island?
