Consider a firm that has cost function C$($q$)$ which is an increasing function of total output produced q$.$ Assume that the firm$$s marginal cost curve m$($q$)$ has positive slope. a$)$ Suppose that output q is sold in a perfectly competitive market. Describe the condition for profit maximization on the part of the firm, and sketch this solution in a graph. b$)$ Suppose that output q is sold in a monopolistic market. Describe the condition for profit maximization on the part of the firm and sketch this solution in a graph.
