A factory has fixed costs of $1,275 per month. The cost of producing each unit of its product is $2.50. Each unit sells for $10. The equations that model the cost and revenue for producing x units are shown. Cost: C(x) = 1275 + 2.5x Revenue: R(x) = 10x If the company sells every unit it produces, how many units must it sell in order to break even? units
