Book Sales As OHaganBooks.com has grown in popularity, the sales manager has been monitoring book sales as a function of the website traffic (measured in thousands of visits per day) and has obtained the following model:
a. On average, how many books per day does the model predict that OHaganBooks.com will sell when it has 60,000 visits in a day? 100,000 visits in a day? 160,000 visits in a day?
b. What does the coefficient 1.75 tell you about book sales?
c. According to the model, approximately how many visitors per day will be needed to sell an average of 300 books per day?
