There are three kinds of guest rooms in a hotel, three of them are 60 yuan per night, two of them are 42 yuan per night, and one of them is 35 yuan per night. If the tour group has 14 guest rooms, the cost is 657 yuan. How many of the three guest rooms are there
Seriously doubt your intention to ask
How many people are there in a tourist group? Don't use the equation,
48 people less than two rooms, more than two rooms, respectively, four rooms different. 6 people to 4 people will spare 2 people, spare 4 * 4 = 16 people. 16 divided by 2 = 8, the original 8 6 people. 8 * 6 = 48 (people) this problem is not so rigorous, does not explain whether each room is full
During the Beijing Olympic Games, a travel agency organized a group to go to Beijing to watch a football match and stay in a hotel. It is known that there are 5 fewer rooms on the first floor than on the second floor. The group has 48 people. If all of them are arranged on the first floor and each room has 4 people, the room is not enough. If all of them are arranged on the second floor and each room has 3 people, the room is not enough and each room has 4 people, there is room Can you confirm the number of rooms on the first floor of the hotel according to the above information?
If there are x rooms on the first floor, then there are x + 5 rooms on the second floor. According to the meaning of the questions, they are: 4x < 48, x < 12, 5x > 48, x > 9.6, and 3 (x + 5) < 48, that is, x < 11, 4 (x + 5) > 48, x > 7
