Rationale for Simplifying the Profit Function
An economist is advising a company on how to determine the number of employees (N) that will maximize its profit (π). The initial profit model is π = 200N - N² - wN, which depends on both the number of employees (N) and the wage (w). The economist also knows that to retain productive workers, the company must set the wage according to the rule w = 20 + N. The economist's first action is to combine these two pieces of information into a single equation: π = 200N - N² - (20 + N)N. Explain the primary analytical advantage of performing this substitution. What does this new, single-variable equation allow the economist to do that the original two-equation model did not?

Finding the Profit-Maximizing Employment Level via Differentiation
In a scenario where two competing local businesses must decide on their advertising spending, a model assuming a single, isolated interaction between purely self-interested parties predicts that both will choose high-spending strategies, resulting in lower profits for both. However, if these businesses are located in a small town and expect to compete for many years, they often end up cooperating by keeping advertising spending low. Which of the following best explains this cooperative outcome, which the simpler model fails to predict?
Simplifying the Profit Function
Deriving a Single-Variable Profit Function
A firm's profit (π) is determined by its revenue and labor costs, represented by the function π = 100N - N² - wN, where N is the number of employees and w is the wage. To ensure employees work effectively, the firm must pay a wage according to the function w = 10 + 0.5N. To find the profit-maximizing level of employment, the first step is to express profit as a function of only N. Which of the following equations correctly represents the firm's profit as a function of N alone?

A manager wants to determine the number of employees that will maximize the company's profit. The manager has a profit equation that depends on both the number of employees and the wage paid, as well as a separate equation showing that the required wage depends on the number of employees hired. Arrange the following steps in the correct logical order to solve this problem.
