For each cost function (given in dollars), find the cost, average cost, and marginal cost at a production level of 1000 units; the production level that will minimize the average cost; and the minimum average cost. C(q) = 8,000 + 350q - 0.3q2 + 0.0001q3 (a) the cost, average cost, and marginal cost at a production level of 1000 units cost $ 158000 average cost $ 100058 X marginal cost $ 350299200 X (b) the production level that will minimize the average cost (Round your answer to the nearest integer.) units (c) the minimum average cost (Round your answer to two decimal places.)
