Need help with #1 please

Rational actors in the economy will only select a choice if the marginal benefits of it are equal to or greater than the marginal costs of the action. In microeconomics, one benefit a firm receives from selling a product is the revenue (price times the quantity). One cost associated with producing a product is the cost of the human resources required to make the product. A rational firm wants to know how many workers it should hire to maximize its profit. Profit is revenue minus costs. An economist would tell the firm to hire the number of workers at which the marginal revenue generated by the human resource is equal to the marginal cost of hiring the human resource. Consider an example in which the wage for each worker you hire is $10.00 an hour and the price of your product is $2.50. In the table below, the marginal revenue (benefit) of each additional worker is equal to the marginal cost of each additional worker when the firm hires worker #3. A rational firm would not hire the 4th worker because the marginal cost of that worker is greater than the marginal benefit Number of Total units Marginal Price of Total Marginal Marginal workers produced Number of Each Unit Revenue Revenue Cost of Units Produced for the for Hiring Each Produced Units Generated Additional Produced by Each Worker Additional Worker 0 $2.50 0 6 6 $2.50 $15.00 $15.00 $10.00 2 11 5 $2.50 $27.50 $12.50 $10.00 15 4 $2.50 $37.50 $10.00 $10.00 18 3 $2.50 $45.00 $7.50 $10.00 5 20 N $2.50 $50.00 $5.00 $10.00 6 21 1 $2.50 $52.50 $2.50 $10.00 1. Define rational actors in an economic setting. Define marginal costs. Define marginal benefit. How does one calculate revenue? What is one cost associated with producing an item? Explain why the firm seen in the chart would only have 3 workers compared to 1, 2, 4, 5, or 6 workers. DO NOT COPY AN ANSWER FROM THE READING FOR THIS QUESTION. Put your answer in your own words
