On the graph input tool, change the number found in the Quantity Demanded field to determine the prices that correspond to the production of 0, 6, 12, 15, 18, 24, and 30 units of output. Calculate the total revenue for each of these production levels. Then, on the following graph, use the green points (triangle symbol) to plot the results. Calculate the total revenue if the firm produces 6 versus 5 units. Then, calculate the marginal revenue of the sixth unit produced. The marginal revenue of the sixth unit produced is________. Calculate the total revenue if the firm produces 12 versus 11 units. Then, calculate the marginal revenue of the 12th unit produced. The marginal revenue of the 12th unit produced is_________.
Calculate Edison's marginal revenue and marginal cost for the first seven frying pans he produces, and plot them on the following graph.

When he does this, the marginal cost of the last frying pan he produces is s which is than the price Edison receives for each frying pan he sells. The marginal cost of producing an additional frying pan (that is, one more frying pan than would maximize his profit) is than the price Edison receives for each frying pan he sells. Therefore, curves. Because Edison is a price which is Edison's profit-maximizing quantity corresponds to the intersection of the taker, this last condition can also be written as
Calculate Iyana's marginal revenue and marginal cost for the first seven rompers they produce, and plot them on the following graph.

Iyana's profit is maximized when they produce a total of is $ , an amount rompers. At this quantity, the marginal cost of the final romper they produce than the price received for each romper they sell. At this point, the marginal cost of producing one more romper (the first romper beyond the profit maximizing quantity) is $ , an amount than the price received for each romper they sell. Therefore, Iyana's profit-maximizing quantity occurs at the point of intersection between the Because Iyana is a price taker, the previous condition is equivalent to curves.
