Arrange the following steps to illustrate the process of profit maximization in a monopoly as seen in the case study of Gary's Gym:

In a monopoly like Gary's Gym, the first step to profit maximization is to determine the demand for gym memberships. This involves understanding how many people are willing to pay different prices for access to the gym. Next, Gary needs to calculate his total costs, which include expenses like staff salaries, equipment, and rent. By comparing total revenue, which is the price multiplied by the number of memberships sold, to total costs, Gary can find the profit. For example, if he charges $50 for a membership and sells 100 memberships, his total revenue is $5,000.
