2. Eastman Publishing Company is considering publishing a
paperback textbook on spreadsheet applications for business. The
fixed cost of manuscript preparation, textbook design, and
production setup is estimated to be $160,000. Variable production
and material costs are estimated to be $6 per book. Demand over the
life of the book is estimated to be 4000 copies. The publisher
plans to sell the text to college and university bookstores for $46
each.
What is the breakeven point?
What profit or loss can be anticipated with a demand of 3800

increased to $50.95 and not affect the anticipated demand of 4000
copies, what action would you recommend? What profit or loss can be
anticipated?
