Epticon is launching some new software. Developing the new software involves a relatively high fixed cost of roughly $16 million. Epticon's marginal cost of producing the software is zero. Having obtained a copyright, Epticon acts as a monopolist in the market for its new software. The following graph shows the demand, marginal revenue (MR), and average total cost (ATC) curves for the software. Keeping in mind that the marginal cost (MC) of production is zero, the profit- maximizing quantity of the software is _____ units, and the profit-maximizing price is _____ per unit of software. On the graph, use the green triangle (triangle symbols) to shade the area that represents consumer surplus at Epticon's profit-maximizing price. Then use the grey rectangle (star symbols) to shade the area that represents total cost at the profit-maximizing output level. Finally, use the orange rectangle (square symbols) to shade the area that represents Epticon's profit at the profit-maximizing price and quantity.
