The problem is: 130 micrograms of thyroxine is needed in her bloodstream. Her doctor prescribed one 100 microgram ,thyroxine tablet to be taken every day. If the half-time of thyroxine is 6.7 days, either justify that the uptake of thyroxine by the body and clearance through the liver fits a model similar to that for renal clearance stated above, or modify the mathematical model (do not alter the dosage or prescribe other drugs) so that it fits the given conditions.
