Suppose that the cost in dollars to produce a batteries is given by C(x) = 0.001123 0.0011x3 -0.43x + 77x+1300. The price-demand function for this type of battery is given by p = 380-5x. Calculate the marginal revenue, marginal cost, marginal average cost, and marginal profit of the 14th battery. R' (13)= = Select an answer C' (13) = '(13)= Select an answer dollars per battery dollars dollars per battery per battery Select an answer P'(13) = Select an answer
