Complete the following problem and submit the file to the appropriate D2L drop box for this assignment.  You must show me your work (computations) in this document in order to earn the credit – using Word’s equation editor might be best.  Handwriting on the screen or uploading a photo of handwritten work is unacceptable.  I expect you to use the editing capabilities of MS Word to complete this problem.  You may copy and paste any work done using other software into this document.  Simply listing a couple of numbers is not acceptable --  I must be able to evaluate your responses.  Balance the line using the editable worksheet on page 2.  Do not change the filename (425Problem4.docx) when you save or submit the file to the dropbox, D2L will add your name to the filename when I download it.
