The point at which a company's profits equal zero is called the company's break-even point. Let R represent a company's revenue, let C represent the company's costs, and let x represent the number of units produced and sold each day.
R(x)=20x C(x)=12.5x+37500
(a) Find the firm's break-even point; that is, find x so that R=C.
(b) Find the values of x such that Upper R(x) greater than C (x right). This represents the number of units that the company must sell to earn a profit.
