Letx= the number of cards printed and sold each month. Therefore, cost is equal to 6000 + 18x,and revenue is equal to 0.30x.You're looking for the point where revenue is greater than the cost (revenue > cost). The inequity is 0.30x> 6000 + 18x.Subtracting 18xfrom both sides of the inequity results in 0.12x>
6000. Divide both sides by 0.12. The result is thatx> 50,000. The printing plant would have to print and sell
50,000 cards per month to make a profit.
