This assignment has two separate problems. Complete the following problems and submit the file (in MS Word format) 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. 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 -- I must be able to evaluate your responses. Do not change the filename
(425Problem10.docx). When you submit the file to the dropbox, D2L will add your name to the filename.
