Using speed as an example, a train moving at a speed of 80 miles per hour would have travelled 80 miles (which is the change in distance covered in the journey) in one hour. Similarly, marginal profit dP dx , marginal revenue dR dx and marginal cost dC dx , respectively, give the approximate change in profit P , revenue R and cost C for each additional unit of goods sold . Example . Mrs. Rose has a business selling pˆat´ e in Tampa for over a year. She wants to study the effect of pricing in her pˆat´ e servings on her business.
