QUESTION #3 DRUG DOSAGES Thomas Young has suggested the follow- ing rule for calculating the dosage of medicine for children 1 to 12 yr old. If a denotes the adult dosage (in milligrams) and if t is the child's age (in years), then the child's dosage is given by at D(t) %3D t + 12 Suppose the adult dosage of a substance is 500 mg. Find an expression that gives the rate of change of a child's dosage with respect to the child's age. What is the rate of change of a child's dosage with respect to his or her age for a 6-yr- old child? A 10-yr-old child?
