The point at which a company's costs equal its revenues is the break-even point. C represents the cost, in dollars, of x units of a product and R represents the revenue, in dollars, from the sale of x units. Find the number of units that must be produced and
sold in order to break even. That is find the value of x for which C=R
C = 13x + 28,000 and R = 15x
How many units must be produced and sold in order to break even?
