Consider the following very simple model of blood cholesterol levels based on the fact that cholesterol is manufactured by the body for use in the construction of cell walls and is absorbed from foods containing cholesterol: Let C(t) be the amount (in milligrams per deciliter) of cholesterol in the blood of a particular person at time t (in days). Then
dC = k1 (C0 - C) + k2E,
C0 = the person's natural cholesterol level,
k1 = production parameter,
E = daily rate at which cholesterol is eaten, and
k2 = absorption parameter
How can I solve this differential equation? It seems as though it is not separable, so I am unsure. I know I want to get C on one side and t on the other, but how do I do this properly since it's not separable (or at least I don't think it is)?
