For high levels of quantity supplied where firms have reached near maximum capacity, supply becomes less elastic because firms may need to invest in additional capital in order to further increase production.

Winston uses the high-low method. it had an average cost per unit of $10 at its lowest level of activity when sales equaled 10,000 units and an average cost per unit of $6.50 at its highest level of activity when sales equaled 20,000 units. what would winston estimate its total cost to be if sales equaled 8,000 units?

5. profit maximization and shutting down in the short run suppose that the market for polos is a competitive market. the following graph shows the daily cost curves of a firm operating in this market. 0 2 4 6 8 10 12 14 16 18 20 50 45 40 35 30 25 20 15 10 5 0 price (dollars per polo) quantity (thousands of polos) mc atc avc for each price in the following table, calculate the firm's optimal quantity of units to produce, and determine the profit or loss if it produces at that quantity, using the data from the previous graph to identify its total variable cost. assume that if the firm is indifferent between producing and shutting down, it will produce. (hint: you can select the purple points [diamond symbols] on the previous graph to see precise information on average variable cost.) price quantity total revenue fixed cost variable cost profit (dollars per polo) (polos) (dollars) (dollars) (dollars) (dollars) 12.50 135,000 27.50 135,000 45.00 135,000 if the firm shuts down, it must incur its fixed costs (fc) in the short run. in this case, the firm's fixed cost is $135,000 per day. in other words, if it shuts down, the firm would suffer losses of $135,000 per day until its fixed costs end (such as the expiration of a building lease). this firm's shutdown price—that is, the price below which it is optimal for the firm to shut down—is per polo.

Parks corporation is considering an investment proposal in which a working capital investment of $10,000 would be required. the investment would provide cash inflows of $2,000 per year for six years. the working capital would be released for use elsewhere when the project is completed. if the company's discount rate is 10%, the investment's net present value is closest to (ignore income taxes) ?
