A commercial aircraft manufacturer has the following two alternatives$$to manufacture security approved cockpit doors to meet the FAA$$s new$$standards for commercial airplanes. The first alternative has a fixed cost$$of $$2,000,000$ with variable cost of $$10,000$ per unit. The second alternative$$has a fixed cost of $$1,200,000$ with variable cost of $$20,000$ per unit. What is$$the break$-$even$$quantity of the cockpit door that allows the aircraft$$manufacturer to be indifferent between these two alternatives?A commercial aircraft manufacturer has the following two alternatives$$to manufacture security approved cockpit doors to meet the FAA$$s new$$standards for commercial airplanes.
