Suppose that this "drip" supplies glucose at the rate of 15 mg per minute, and each minute 20% of the accumulated glucose is consumed by the body. Then the amount y(t) of glucose (in excess of the normal level) in the body after t minutes satisfies the following. y' = 15 − 0.2y (Do you see why?) y(0) = 0 (zero excess glucose at t = 0) Solve this differential equation and initial condition.
