Total revenue equals A. change in price per unit times quantity sold. B. price per unit times change in quantity sold. C. price per unit times quantity sold. D. price per unit times quantity supplied.

C. price per unit times quantity sold.

Explanation:

Total revenue is defined as the revenues that are received from the sales of units of goods and services. It is price multiplied by quantity sold.

Total revenue can also be seen as price per unit times quantity is sold. For example if the unit price of a good is $2 the price per one unit is $2. When 20 units are sold the price per units sold is 20 * $2 = $40.

So times that a defined unit of goods is sold multiplied by price gives the total revenue.
