It costs a publisher $74,200 to prepare a book for publication (typesetting, illustrating, editing, and so on); printing and binding costs are $5.50 per book. The book is sold to bookstores for $19.50 per copy.

a. Make a table showing the cost of producing 2,000, 4,000, 6,000, and 8,000 books.

b. Make a table showing the revenue from selling 2,000, 4,000, 6,000, and 8,000 books.

c. Write an algebraic expression representing the cost y as a function of the number of books x that are produced.

d. Write an algebraic expression representing the revenue y as a function of the number of books x sold.

e. Graph both functions on the same coordinate axes.

f. Use TRACE and ZOOM to find where cost equals revenue.

g. Use the graph to determine how many books need to be made to produce revenue of at least $85,000. How much profit is earned for this number of books?
