1.1. The loss-minimizing point is where marginal revenue (MR) equals marginal cost (MC).

Here are the answers to your questions based on the graph:

2.1.1. The loss-minimizing point is where marginal revenue (MR) equals marginal cost (MC).

• This occurs at point c on the graph.
• c

2.1.2. To find the selling price, first identify the output level where MR = MC (point c), which is 100 units. Then, find the corresponding price on the demand (DD/AR) curve at that output level.

• At a quantity of 100, the price on the DD/AR curve is 150.
• 150

2.1.3. A monopoly is a market structure where a single firm is the sole producer of a unique product with no close substitutes, and there are significant barriers preventing new firms from entering the market.

2.1.4. The equilibrium position shown in the graph (where the firm is making a loss) is typical of the short run because, in the long run, firms experiencing sustained losses would exit the market. In the short run, a firm might continue to operate at a loss if its price covers its average variable costs, hoping for market conditions to improve.

2.1.5. To determine the loss, we need the average cost, average revenue (price), and quantity at the equilibrium point.
