10. accounting LLA Return to the above problem dealing with Ralph’s cost curve. Now suppose Ralph’s accountant approximates CSR(q; P) with an LLA of CSR(q; P) ≅ a +bq. Further suppose the accountant does this by setting the slope of the LLA equal to the marginal cost at q = 10 and so that the total cost at q = 10 equals the approximate cost at that point: CSR(10; P) = a + b(10). Graph the LLA. What is its slope? What is its intercept? Over what range does this strike you as a reasonable approximation to the underlying short-run and long-run cost curves? Is the intercept a fixed cost?
