(1 pt) Consider a drug that is taken in 55 mg doses daily. Suppose that the first dose is taken when t = 0 and that t is measured in hours. A.If the half-life of the drug is 6.7 hours, what fraction of the drug remains in the patient after 24 hours? fraction = B.Write a general expression for the amount of the drug in the patient immediately after taking the nth dose of the drug. An = C.Write a general expression for the amount of the drug in the patient immediately before taking the nth dose of the drug (for this we only consider n > 1). Pn = D.What is the long-term minimum amount of drug in the patient? Long-term minimum = mg 0 t (Click on graph to enlarge)
