Problem 17 The Harris Hotel forecasts its breakfast customers based on (1) its prior night room guests count, (2) an estimated number of diners from the local community, and (3) an estimated number of guests who are staying at a nearby limited-service hotel and will have breakfast at the Harris Hotel.
