In order to better understand the profitability of the business, the owners asked you for an analysis of costswhat 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.
