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 into account the Biblical Parable of Wise and Foolish Virgins (Matthew 25:1-13), what are the implications of preparation and planning? Explain in many details.
