This text presents a wide variety of common types of models found in other mathematical modeling texts, as well as some new
types. However, the models are presented in a very unique format. A typical section begins with a general description of the
scenario being modeled. The model is then built using the appropriate mathematical tools. Then it is implemented and analyzed
in Excel via step-by-step instructions. In the exercises, we ask students to modify or refine the existing model, analyze
it further, or adapt it to similar scenarios.
