Hotel manager Basil Fountain and his resourceful assistant, Casey,  run a 26-room hotel in a quaint little town called Poynette.  A combination of Mr. Fountain’s friendly attitude and the absence of a respectable inn in the nearby vicinity imply that Mr. Fountain enjoys sufficient demand to fill the hotel at his low fare of $159 per night.  Casey notes that some customers will walk into the hotel requesting a room for the night and that they are willing to pay a higher fare of $325 per night.  Casey knows that walk-in customer demand varies according to a normal distribution with a mean of 7 and a standard deviation of 2.75.  She suggests that some rooms should be held back from the low-fare customers so that they can serve the high-fare customers.  To maximize expected profits with Casey’s plan, what is the booking limit that should be set for low-fare customers?
