The decision-making game is built on a model which adheres to the economic principles of supply and demand. Game participants are faced with the task of generating profit in a simulated competitive situation. The game provides the opportunity for participants to gain a greater understanding of: (1) the relationship between income and costs and resulting profit, (2) the complexity of the buying process, and (3) the income statement. An instructor's guide, worksheets for game players, and teacher information forms are included in the manual. (VA)
