Profit Maximization Marginal revenue is the change in revenue which comes from the sale of an additional unit of output. The relationship with total revenue is that total revenue is used in the formula to calculate marginal revenue. A company can calculate marginal revenue by dividing the change in total revenue with the change in output quantity. Because of demand‚ as production quantity increases the revenue per unit will decrease. On the other hand‚ marginal cost is the change in the total

past‚ transportation management was a tactical concern – a necessary cost of conducting business‚ which does not have much impact on profit margins. Today‚ rising fuel prices and increased pressures for improved service have made transportation management a strategic issue. Companies have to meet and exceed customer expections if they are to be the preferred service and goods provider. A transportation management system (TMS) is an end- to -end software solution that is a part of supply chain

2) Explain why a profit maximizing firm produces the output that equates marginal revenues to marginal costs (MR=MC). In a perfectly competitive market‚ producers are price-takers and consumers are price-takers. There are many producers‚ none having a large market share and the industry produces a standardized product‚ also free entry and exit of the industry. They produce using the optimal output rule: produce where marginal revenue equals marginal cost as Smith (1904) demonstrated. Figure
