Let adults x people, then children is 18-x. the equation is: 35x + 35 / 2 (18-x) = 525. 35x-17.5x + 315 = 525, 17.5x = 210, x = 12. So there are 12 adults and 6 children



During May Day, Xiao Ming, Xiao Liang and other students went to a park with their parents. The following is a dialogue between Xiao Ming and his father when buying tickets

[[please,]] use the equation of one yuan per time ~ don't copy it~


(1)
If there are x adults, the students have (12 - x) and (12 - x)
40 * x + 20 * (12 - x) = 400, i.e
240 + 20*X = 400
20*X = 160
X = 8
12 - X = 4
There are eight adults and four students
(2)
It's cheaper to buy group tickets, which costs 16 * 40 * 0.6 = 384 yuan
Hope it helps



During the Dragon Boat Festival, Xiao Ming, Xiao Liang and other students go to Taishan with their families. It is known that the ticket price is 35 yuan for an adult, 50% discount for students, and 60% discount for group tickets for more than 16 people (including 16 people), It's 350 yuan in total. Xiaoming: Dad, let me calculate. Is it cheaper to buy tickets in another way? How many students? (2) Please help Xiao Ming figure out which way to buy tickets is more economical? And why?


(1) Let x adults go, according to the meaning of the question, the equation is 35x + 35 × 12 (12-x) = 350, the solution is x = 8, the number of students is 12-8 = 4. (2) if you buy a group ticket, you need to spend 16 × 35 × 60% = 336 (yuan), because 336 < 350, so you can save more money



During the women's day on March 8, a unit organized female employees to visit the "star bamboo sea" in hot spring. The following is a dialogue between the neighboring teams and the tour guide's charge standard of the travel agency: neighboring teams: how much is the charge per person for a group tour to the "Star bamboo sea"? Tour guide: if the number of people is less than 25, the per capita travel cost is 100 yuan? Tour guide: if there are more than 25 people, the per capita travel expenses will be reduced by 2 yuan for each additional person, but the per capita travel expenses shall not be less than 70 yuan. The unit will pay 2700 yuan to the travel agency after visiting the "star bamboo sea" according to the fee standard of the travel agency. According to the above information, please ask how many people the unit has visited the "star bamboo sea" this time?


Suppose that there are x people in the unit participating in this tour, ∵ 100 × 25 ∵ 2700 ∵ x > 25. According to the meaning of the title, we get [100-2 (x-25)] x = 2700, sort out x2-75x + 1350 = 0, and solve X1 = 30, X2 = 45. When x = 30, 100-2 (x-25) = 90 > 70, which is in line with the meaning of the title. When x = 45, 100-2 (x-25) = 60 < 70, which is not in line with the meaning of the title



The ticket price regulations of children's Park are as follows: ticket number: 1-50 people: 51-100 people: ticket price: 13 yuan per person for more than 100 people: 11 yuan per person; A total of 104 students from Class A and class B of Grade 7 of a school went to the children's Park. The number of students in class A was less than 50, while the number of students in class B was more than 50. If the two classes bought tickets separately, they would have to pay a total of 1240 yuan? (2) How much money can you save if you buy tickets as a group?


(1) Suppose there are X students in class A, then there are (104-x) students in class B. according to the meaning of the question, we get: 13X + 11 (104-x) = 1240, and the solution is: x = 48104-x = 104-48 = 56. Answer: there are 48 students in class A and 56 students in class B. (2) according to the meaning of the question, we get: 1240-9 × 104 = 304 (yuan). Answer: if two classes buy tickets together as a group, we can save 304 yuan



There are a number of students (more than 100) in class 1 and class 2 of Grade 7 in a school who go to the park. The number of students in class 1 is less than 50, and that in class 2 is 50
If the two classes usually buy tickets separately, they will pay 1240 yuan by supply. If the two classes unite to buy tickets as a group, they will save 304 yuan. How many students are there in each class
The number of tickets purchased is 50, 51-100, more than 100
The price of each ticket is 13 yuan, 11 yuan and 9 yuan


Let x people in class 1, y people in class 2, simultaneous equation 9 (x + y) = 1240-304, 13X + 11 (104-x) = 1240, the solution is x = 48, so there are 48 people in class 1 and 56 people in class 2



The ticket price regulations are listed in the table below. There are 104 students in grade seven (1) and (2) classes of a certain school to visit the park, of which (1) class has a small number, less than 50 students, and (2) class has a large number, 50 students
More than one person. It is estimated that if the two classes buy tickets separately on a shift basis, they will pay a total of 1
How many students are there in each class? (2) 104 students in each class go to the park, of which (1) class
There are more people, more than 40, less than 50. It is estimated that if the two classes buy tickets separately, they will pay a total of 1240 yuan
Ticket number: 50, 51 ~ 100, more than 100
Ticket price per person: 13 yuan, 11 yuan, 9 yuan (Note: the equation should be made once every one yuan!)
1. How many students are there in these two classes?
2. How much money can you save if the two classes join together to buy tickets as a group? 3. If class 1 of Grade 7 organizes to visit the garden alone, how can you save the most money by buying tickets as an organizer


(1) There are X students in class 1 of Grade 7,
Then 13X + 11 (104-x) = 1240,
The solution is: x = 48
There are 48 students in class 1 of Grade 7 and 56 students in class 2 of Grade 7;
(2)1240-104×9=304,
It can save 304 yuan;
(3) If you want to enjoy the discount, you only need to buy three more tickets for 48 students in class 1 of Grade 7,
51×11=561,48×13=624>561
48 people can save more money by buying tickets for 51 people

Group ticket for 20 people is cheaper than individual ticket? Use one yuan inequality system! Urgent


Suppose the team has n people (N10 * 0.8 * 20, that is, 10N > 160, that is, n > 16), so when the team number is 17-19, it is cheaper to buy team tickets than individual tickets!
