A doctor prescribes a 200 mg antibiotic tablet to be taken every eight hours. It is known that the body eliminates 80% of the drug in eight hours. (a) How much of the drug is in the body just after the second tablet is taken? After the third tablet? second tablet x mg third tablet X mg (b) If Q, is the quantity of the antibiotic in the body just after the nth tablet is taken, find an equation that expresses Q, +1 in terms of Qn: Qn + 1 (c) What quantity of the antibiotic remains in the body in the long run? mg
