Final answer:
Calculating the profit of a monopolist requires knowing the total revenue (price times quantity) and total costs (average cost times quantity). The question lacks key information such as the price and the cost structure, which makes it impossible to calculate the exact profit with the detail provided.
Step-by-step explanation:
To calculate the profit of a monopolist, we need to determine the total revenue and total cost. The profit-maximizing quantity for the monopolist, given as 2 units, is where marginal revenue (MR) equals marginal cost (MC). Unfortunately, the information provided is insufficient to calculate profit directly, as we need additional data like the price at which the monopolist sells the 2 units of the product and the average total cost at that level of output.
If we had the price, we could calculate total revenue by multiplying the price by the quantity sold (2 units). We would also need the average total cost of producing 2 units to calculate the total cost, which we would then subtract from total revenue to find the profit. Since the demand curve intersects with the price axis at 15 and the quantity axis at 7.5 units, we can infer that the price at the quantity level of 2 units would be higher than the price associated with 7.5 units due to the downward-sloping demand that a monopolist typically faces. However, without more details on the actual costs or prices, we cannot determine the exact amount of profit.
