Question: In figure 15-5, suppose for each patient that marginal cost = $100 and estimates of utilizations rates are R₁ = 1, R₂ = 2, and R₃ = 3. Suppose also that one-third of the physicians use treatment levels R₁, R₂, and R₃, each. What would be the “cost per patient” of SAV, if all of the demand curves have slopes of -50? (Hint: Use the parameter estimates to figure out the sizes of triangles A and B.)
