Process the attached three documents. The attached Excel Spreadsheet is one which you have completed for a previous assignment. When using this Excel Spread sheet for a "Help Me Solve This Problem" assignment, I replaced the data with the current assignment (see attachment); however, the solutions were not correct. If you would modify the original worksheet by inputting the data for Attachment a for one of the Excel Spreadsheets, and then modify the original Excel spreadsheet once more by inputting the data for attachment b this will be most helpful for me to analyze and then perhaps be able to find the correct solution. All three spreadsheets should be in an Excel Book.
