a. i. Profit-maximizing output level is whenever Marginal Revenue (MR) = Marginal Cost (MC).
From the graph, you can see when the two curves intersect, quantity (units of output sold) is 15. Therefore, 15 is the profit maximizing output level.

ii. To get Profit-maximizing price, at output = 15, go up to the demand curve (draw a straight line going upward at 15). The line crosses demand curve at 13 on the vertical axis. This firm will charge that ...

This solution discusses how firms are trying to differentiate their products in the monopolistically competitive industry. If they successfully differentiated their products, they can behave like a monopoly by capturing the whole market. As a monopoly, firms are able to charge at a higher price according to demand and making more profits.
