An economist estimated that the cost function of a single-product firm is: C(Q) = 60 + 30Q + 25Q2 + 5Q3. Based on this information, determine the following: a. The fixed cost of producing 10 units of output. $ b. The variable cost of producing 10 units of output. $ c. The total cost of producing 10 units of output. $ d. The average fixed cost of producing 10 units of output. $ e. The average variable cost of producing 10 units of output. $ f. The average total cost of producing 10 units of output. $ g. The marginal cost when Q = 10.
