The profit is calculated by subtracting total cost from total revenue ($1200 - $400 = $800). If they make the price of the product equal the marginal cost of producing the product (MR=MC), it would result in the most efficient output and a maximization of profit. The dead-weight loss is the triangle between the demand and supply curves (competitive market equilibrium) and the vertical line Qm. producer in the market. draw a marginal cost curve. In your graph identify the price, quantity, area of consumer surplus, area of producer surplus, and area of deadweight loss. You can also use the area of a rectangle formula to calculate loss!
