Answer:
c. the slope of the total revenue curve at a given point.
Step-by-step explanation:
Cost-volume-profit analysis is also known as the break even analysis, it is an important tool in predicting the volume of activity, the costs to be incurred, the sales to be made, and the profit to be earned is. It is used to determine how changes in differing levels of activities such as costs and volume affect a company's operating income and net income.
Marginal cost can be defined as the additional or extra cost that is being incurred by a company as a result of the production of an additional unit of a product or service.
Generally, marginal cost can be calculated by dividing the change in production costs by the change in level of output or quantity.
Marginal revenue can be defined as the additional amount of money that is gained or generated by a business firm from the sales of an additional unit of a product or service.
Marginal revenue, graphically is the slope of the total revenue curve at a given point.
This ultimately implies that, the change in the value of the total revenue curve at a given point gives the marginal revenue.
