(F) In 2009, the average room rate for the Marriott in beautiful downtown Uniondale was $ 139.99. According to the better model, how much above the avg. room rate (in dollars) for the United States was this price? 08.28 2 VS. (G) The Great Wolfe Lodge in the Poconos average room rate for 2013 was $425. Find the percent increase from the model you are using to the Great Wolfe Lodge's price. (H) Hotels usually offer employee discounts to their employees who wish to use their hotel. Using the better model, if a hotel offers a 10 % discount, how much would an employee have to pay for an average room in 2013?
