The point at which a company's cost equal its revenues is its break-even point. C represents the cost, in dollars, of X units of a product and R represents the revenue, on 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 + 48,000 and R = 17x. How many units must be produced and sold in order to break-even?
