Marginal Analysis
A manufacturer estimates that if x units of a particular commodity are produced, the total cost will be C(x) dollars, where
C(x) = x^3 - 24x^2 + 350x + 338
a) At what level of production will the marginal cost C'(x) be minimized?
b) At what level of production will the average cost
A(x) = C(x) / x be minimized?
