Problem: In a big city, two companies X and Y are competing for business. They have one store each. Under current conditions they share the total sales of $800,000 equally. Company X is planning to open one or two more stores, or may continue with the existing store (no new stores). Company Y can open only one additional store, or may continue with the existing store (no new stores). Each new store costs $50,000 to build. If they have the same number of stores the companies will share the total sales equally; if one company has one more store than the other it will have 55% of the total sales; if one company has two more stores than the other one it will have 65% of the total sales.
