Questions:

1. Caroline, the production manager, is doing some cost analysis for producing a new textbook. Assume that the cost formula is C = 10x + 350,000. If the textbooks were priced at $40, how many textbooks need to be sold so that the revenue equals the cost?
   
   Answer
   
   
2. Using the information Caroline has already calculated (see above problem), she will produce enough textbooks so that the revenue will exceed the production costs by $100,000. To accomplish this, how many textbooks should she produce?
   
   Answer
   
   
3. After all of the work Caroline has done, a memo comes from her boss with directions to produce 25,000 textbooks. While the production costs will still be the same, the retail price will be determined such that revenue will exceed cost by $200,000. Based on this new information, what will be the retail price for each book?
