Blue Skies Aviation is a manufacturer of small single-engine airplanes. The company is relatively small and prides itself on being the only manufacturer of customized airplanes. The companys high standard of quality is attributed to its refusal to purchase engines from outside vendors, and it preserves its competitive advantage by refusing to sell engines to competitors. To achieve maximum efficiencies, the company has organized itself into two divisions: a division that manufactures engines and a division that manufactures airplane bodies and assembles airplanes. Consultants have estimated that: Demand for Blue Skies customized planes is given by P = 812,000 3,000Q. The cost of producing engines is Ce(Qe) = 5,000Qe2, and the cost of assembling airplanes is Ca(Q) = 12,000Q.
