Tutorial Exercise If the recommended adult dosage for a drug is D (in mg), then to determine the appropriate dosage c for a child of age a, pharmacists use the equation c = 0.0417D(a + 1). Suppose the dosage for an adult is 300 mg. (a) Find the slope of the graph of c. What does it represent? (b) What is the dosage for a newborn? Step 1 (a) Find the slope of the graph of c. What does it represent? We are given D = 300. Substitute 300 for D in the equation c = 0.0417D(a + 1). After simplifying, we get c = 0.0417(300)(a + 1) a +
