=E*4.12. Refer to the spreadsheet file named “Everglade Problem 4.12” contained on the CD-ROM. This file contains a formulation of the Everglade problem considered in this chapter. However, three errors are included in this formulation. Use the ideas presented in Section 4.4 for debugging a spreadsheet model to find the errors. In particular, try different trial values for which you can predict the correct results, use the toggle to examine all the formulas, and use the auditing tools to check precedence and dependence relationships among the various changing cells, data cells, and output cells. Describe the errors found and how you found them.
