Find the marginal average cost function if cost and revenue are given by C(x) = 167 + 5.2x and R(x) = 3x - 0.05x2. E) The marginal average cost function is (2'(x) = D. Find the average cost function if cost and revenue are given by C(x) = 173 + 2.2x and R(x) = 9x - 0.02x2. The average cost function is 5(x) = D. The total cost (in dollars) of producing x food processors is C(x) = 2200 + 80x - 0.4x2. (A) Find the exact cost of producing the 81st food processor. (B) Use the marginal cost to approximate the cost of producing the 81st food processor. . . . (A) The exact cost of producing the 81st food processor is $Find the marginal prot function if cost and revenue are given by C(x) = 154 + 0.7x and R(x) = 7x - 0.04x2. P'(x) = D Find the prot function if cost and revenue are given by C(x) = 136 + 1.5x and R(x) = 2x - 0.08x2. E The prot function is P(x) = D
