Final answer:
A monopolist determines its profit-maximizing level of output using the demand curve, decides on the price to charge based on market demand, and calculates total revenue, total cost, and profit.
Step-by-step explanation:
Step 1: The monopolist determines its profit-maximizing level of output by using the points on the demand curve to calculate total revenue and then calculating the marginal revenue curve.
Step 2: The monopolist decides what price to charge based on what the market is willing to pay.
Step 3: The monopolist calculates total revenue, total cost, and profit by multiplying the quantity sold by the price to get total revenue, and then subtracting total costs to get profit.
