Problem: Even though independent gasoline stations have been having a difficult time, Susan Solomon has been thinking about starting her own independent gasoline station. Susan's problem is to decide how large her station should be. The annual returns will depend on both the size of her station and a number of marketing factors related to the oil industry and demand for gasoline. After a careful analysis, Susan developed the following table: SIZE OF First Station GOOD MARKET($) FAIR MARKET($) POOR MARKET($) Small 50,00020,000 -10,000 Medium 80,00030,000 -20,000 Large 100,000 30,000 -40,000 Very large 300,000 25,000-160,000 For example, if Susan constructs a small station and the market is good, she will realize a profit of $50,000.
