Hospital patients are often given glucose (blood sugar) through a tube connected to a bottle suspended over their beds. 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.

Hospital patients are often given glucose (blood sugar) through a tube connected to a bottle suspended over their beds. 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.
