Math 464, Worksheet 8 Suppose that a population is divided into M mature animals and A adolescents. Assume the following conditions (as represented in the diagram below): Birth rate is b = 0 . 1 adolescents per day per mature animal. Death rate for adolescents is d A = 0 . 01 per day per adolescent. Death rate for mature animals is d M = 0 . 05 per day per mature animal. Adolescents mature into adults at a rate of g = 0 . 1 per day per adolescent. d A A b g M d M 1. Write diFerence equations for A and M . 2. Assuming A (0) = M (0) = 50, compute
