This is a spreadsheet tutorial of an example of implementing models in spreadsheets. These models are from the area of management science. In this example, the owner's goal is to know how much to produce throughout the month so that he can predict his profit and set the price. To do this, he wants to go beyond traditional profit projections, so he creates a model in a spreadsheet. The model is explained in this blog post and is provided as a reference tutorial.
 Note: The spreadsheets available for download are based on references from blog posts and should be viewed only as supplementary study material. We do not offer support for technical questions regarding the theoretical content of the spreadsheets. This material does not exempt the user from adequate monitoring by a professional in order to obtain greater reliability, both in execution and in calculations.
