If you solved the problem or part of the problem in Excel, show your work in Excel by organizing your analysis clearly

• Clearly show how you solved each problem and highlight your final answers.
• Use brief text box annotations if necessary.
• Merge worksheets from separate files into a single Excel workbook with one tab for each problem.
  • How to copy Excel worksheets into a single workbookLinks to an external site.

If you solved the problem or part of the problem by hand

• Show you work using the three-step approach
  • Step 1: Write the algebraic formula you use to solve the problem.
  • Step 2: Rewrite the formula substituting in the numbers from them problem.
  • Step 3: Write your final answer.
• You may scan and upload images of your handwritten work and insert them into your Excel file.
• If typing your analysis, type the formulas as you would in a basic word processor or copy and paste from a word processor or text box.
  • e.g. Problem 1: EOQ = sqrt(2*D*S/H) = sqrt(2*12000*4000/100) = 979.8
