Walter Silva runs operations at Firestone Clock Company. The company currently owns and operates its own manufacturing facilities that produce three lines of clocks, Desktop Models, Wall Units, and Custom Clocks. Manufacturing and other costs have been rising, and profits are being squeezed. Walter has asked you to create a workbook that details the financial components of each product line, then analyze a number of scenarios that involve cutting expenses and/or raising prices. You are trying to find the most profitable mix of products using the most cost-effective means of production.
