Before publishing a hardcover book, a publisher wants to determine the proper price to charge for the hardcover and paperback versions. The fi le paperback .xlsx contains the valuations of 50 representative potential purchasers of the book. Suppose the unit cost of the hardcover book is $4 and the unit cost of the paperback is $2.
If the bookstore charges double what it pays the publisher, what price should the publisher charge the bookstore for each version of the book?
