National Training recently started a business providing training events for corporations. In order to better understand the profitability of the business, the owners asked you for an analysis of costs-what costs are fixed, what costs are variable, and so on, for each training session. You have the following cost information:

Trainer: $11,000 per session

Materials: $2,500 per session and $35 per attendee

Catering Costs (subcontracted):

Food: $75 per attendee

Setup/cleanup: $25 per attendee

Fixed fee: $5,000 per training session

National Training is pleased with the service they use for the catering and have allowed them to place brochures on each dinner table as a form of advertising. In exchange, the caterer gives National Training a $1,000 discount per session.
