The Target Market is for the 1 semester principles of microeconomics course.

One of the all time best-sellers, this text is widely used because of its careful, streamlined, and intuitive chapter organization.

Case & Fair, present a very precise and simplified microeconomic model first, before introducing all the exceptions and subtleties of a more complex economic world.  Only after this simplified model is developed, do the authors give a thorough treatment of market imperfections, externalities, public finance, and international economics.  (A detailed summary of this approach can be found on the page directly following the inside front cover).
