In addition, regarding consumer and producer surplus: Let us consider the effect of a new after-tax selling price of $7.50: The price would be $7.50 with a quantity demand of 450.

Let's say we're the owners of this firm and we have a marginal cost curve that looks something like this. supply for the market and we have this downward sloping marginal revenue curve. Once we have determined the monopoly firm's price and output, we can determine its economic profit by adding the firm's average total cost curve to the graph showing demand, marginal revenue, and marginal cost, as shown in Figure 10.7 "Computing Monopoly Profit". Similarly, governments often fix a minimum wage for laborers and employees. Deadweight loss refers to the cost borne by society when there is an imbalance between the demand and supply. A monopolist maximizes profit by producing the quantity at which marginal revenue and marginal cost intersect. So yes, if you want to find out the marginal revenue of the 5th unit, you would subtract Total revenue of the 5th unity by the total revenue of the 4th unit, i wondering whether all these fancy graphs are really necessary to explain relatively straightforward ideas.
