Managerial Accounting Discussion need done ASAP in 3 hours

Please Complete my discussion, must meet all guidelines!

For each of the following companies, identify which one you would expect to have a higher contribution margin, and discuss your selection: 1) PepsiCo versus Wal-Mart; 2) Amazon.com versus Macy's; 3) Safeway versus Ford Motor Company; 4) Delta Airlines versus Burger King.   Is it possible for an established organization to change their contribution margin?  What is the impact of below average break-even sales over an extended period of time?  And, taking in to account the Biblical Parable of Wise and Foolish Virgins (Matthew 25:1-13), what are the implications of preparation and planning?  Include a minimum of one scholarly peer reviewed journal reference and one theological reference in the response.  (300-400 word count range).

You may use the following links to help find theological references: http://www.openbible.info/topics/ and http://www.biblestudytools.com/topical-verses/
