Assume that you are preparing a seminar on cost-volume-profit analysis for nonaccountants. Several potential attendees have approached you and have asked why they should be interested in learning about your topic. The individuals include the following:

• A factory worker who serves as her companys labor union representative in charge of contract negotiations.
• A purchasing agent in charge of ordering raw materials for a large manufacturing company.
• A vice president of sales for a large automobile company.
• A director of research and development for a pharmaceutical company.

What unique reasons could you give each of these individuals to motivate them to come to your seminar?
