Question

The point at which a company’s profits equal zero is called the
company’s break-even point. For Problems 43 and 44, 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.
(a) Find the firm’s break-even point; that is, find x so that R = C.
(b) Find the values of x such that R(x) > C(x). This represents
the number of units that the company must sell to earn a profit.
43. R(x) = 8x
C(x) = 4.5x + 17,500
44. R(x0 = 12x
C(x) = 10x + 15,000
