Question

Define Q to be the level of output produced and sold, and assume that the firm's cost function is given by the relationship TC = 20 + 5Q + Q^2. Furthermore, assume that the demand for the output of the firm is a function of price P given by the relationship Q = 25 - P. a. Define total profit as the difference between total revenue and total cost, and express the total profit function for the firm in terms of Q. (Note: Total revenue equals price per unit times the number of units sold.) b. Determine the output level where total profits are maximized. c. Calculate total profits and selling price at the profit-maximizing output level. d. If fixed costs increase from $20 to $25 in the total cost relationship, determine the effects of such an increase on the profit-maximizing output level and total profits.
