For each of the total cost functions, write the expressions for the total fixed cost, average variable cost, and marginal cost (if not given), and draw the average total cost and marginal cost curves.

TC (q) = 10Q

TC (q) =16 + 10Q

TC (q) = 10Q2, where MC (q) = 20Q

TC (q) = 160 + 10Q2 where MC (q) = 20Q
