Required Mathematical Intelligence

Chapter 135

Join us as we test run an 80-suite hotel and see how knowledge can turn into wealth.After investigation, we found that if we set the daily rent at 160 yuan, we would be full; and for every 20 yuan increase in rent, we would lose 3 customers.A total of 40 yuan is required for daily service and maintenance of each guest room.Question: How should we price it to make the most money?
[答案：日租金360元。虽然比客满价高出200元，因此失去30位客人，但余下的50位客人还是能给我们带来360×50=18000元的收入；扣除50间房的支出40×50=2000元，每日净赚16000元。而客满时净利润只有160×80-40×80=9600元。]
