Park ticket prices are set out in the table below Number of tickets purchased: 1-50, 51-100, more than 100 Price of each ticket: 13 yuan, 11 yuan, 9 yuan A total of 104 students from seven (1) and two (2) classes of a school went to visit the park, of which the number of students in class (1) was less than 50 ① How much money can be saved if the two classes unite to buy tickets as a group? ② How many students are there in each class? ③ If class 7 (1) organizes a tour to the park alone, how can you save money by buying tickets

1、
104*9 = 936
1240 - 936 = 304
It can save 304 yuan
2、
There are less than 100 students in both classes,
If all tickets are purchased at 11 yuan, then 104 * 11 = 1144,
Therefore, if the extra payment is 1240-1144 = 96 and the extra payment is 2 yuan per ticket, then
(1) Class size: 96 / 2 = 48
(2) Class size: 104-48 = 56
In addition, let (1) class number x, then 13 * x + 11 * (104-x) = 1240, that is 1144 + 2x = 1240, and the solution is x = 48
3、
(1) The actual fare for the class is 48 * 13 = 624 yuan. If you buy 51 tickets, it costs 561 yuan, which is cheaper
Hope it helps

The ticket prices of parks in a city are shown in the table below
The ticket prices of a park in Changsha are as follows:
The number of tickets purchased is 1-50, 51-100 and more than 100
Ticket price: 10 yuan / person, 8 yuan / person, 5 yuan / person
More than 100 students from Class A and class B of Grade 7 of a school went to the park to hold a party. Among them, there were more than 50 students from Class A and less than 50 students from class B. if each class bought tickets separately, the two classes would pay 920 yuan in total. If the two classes bought tickets together as a group, they would only pay 515 yuan in total?

The total number of class A and class B is 515 △ 5 = 103
There are X students in class A and 103-x students in class B
From the meaning of the title
8X+10（103-X）=920
8X+1030-10X=920
2X=110
X=55
103-X=103-55=48
A: there are 55 in class A and 48 in class B

Math problem: tickets are 10 yuan per person, and 20% discount for more than 50 people. If group tickets are cheaper than individual tickets, how many people are there in the team at least?

Let X be a person. When x is 50, it is obvious that x is true

The ticket price of a park is as follows: 10 yuan per person for less than 40 people, 10% discount for more than 40 people, and 20% discount for more than 80 people
A total of 101 people from class 1 and class 2 of Grade 7 go to the park. If the number of people in class 1 is more than that in class 2, if both classes buy tickets by class, they will pay a total of 948 yuan
(1) How much money can be saved if the two classes are combined to buy tickets as a group?
(2) How many students are there in each class?

This problem is really not simple. I tried it for a long time
Suppose the number of students in class one is x and the number of students in class two is y
Thus, according to the known conditions, x > y and X + y = 101
Now the question is how to set up another equation according to the price of the ticket
Assuming that the number of class one and class two is almost the same, they are between 40 and 80, and should be given a 10% discount
That formula should be (x + y) = 948, but it can't get an integer after simplification
This formula must be 9x + 10Y = 948 to get the correct answer after bringing in X + y = 101
After solving the equation (I don't need to teach you this), we get x = 62, y = 39
It can be checked that 62 + 39 = 101, and 62 (9) + 39 (10) = 948
If you buy group tickets together, you can save 948 - 8 (101) = 140 (yuan)
The number of students in the two classes is 62 in class one and 39 in class two
Hope to be helpful to you, if you still don't understand, please don't hesitate to ask

The ticket price of a park is as follows: the ticket price is 10 yuan per person. More than 40 people (including 40 people) enjoy group discount, including 10% discount for all members of 40-59 people, and 20% discount for all members of 60 people (including 60 people). Class 1 and class 2 of Grade 7 have 83 people going to the park. It is known that there are more people in class 1 and class 2, but less than two-thirds of the total number, The total payment is 786 yuan
(1) How much money can be saved if the two classes join together to buy tickets as a group?
(2) How many students are there in each class?

Two classes with 83 people, more than 60 people, so 20% off, is 83x10x0.8 = 664. Save how much, use 786-664 = 122 yuan
If there is one class of X, the second class will be 83-x
Column inequality
It is known that there are more people in class one than in class two, so x > 83-x, let's solve x > 83 / 2, that is, x > 41 is more than 1
But less than two-thirds of the total, so X

A kind of mineral water is sold for 2 yuan per bottle at retail. In order to thank customers for their great love for the product, the manufacturer specially carried out the activity of "buy three and get two free" to reward the customers
What's the discount rate?

Three bottles is 6 yuan, [2 - (6 / 5)] / 2 equals 12 / 5 equals 0.4. That's a 40% discount!

A kind of mineral water, retail 2 yuan per bottle, manufacturers in order to thank the vast number of customers for the love of the product, specially carry out "buy four get one free" big reward activities, 48 people in the class each buy a bottle, how much does it cost at least

Suppose: at least x people in the class have to pay for it,
X + X / 4 = 48
The solution is: x = 38.4
The ending method is used here, and the result is: x = 39
So the cost is: 39x2 = 78 (yuan)
A: it costs at least 48 yuan to buy one bottle for each of the 48 students in the class
Hope to help you.

"Thanksgiving we are in action" parents feel after listening! Urgent need! Thank you!

Thank your parents
The greatest kindness in the world is the nurturing kindness of our parents. We should cherish it with our lives, appreciate it with our sincere heart, and repay it with our practical actions
"Sheep have the feeling of kneeling milk, crows have the meaning of regurgitation." and people should also be filial. Don't wait until you want to be filial and your parents are away, leaving a big legacy of life. If you don't regret in the future, you should thank your parents from the little things around you and repay them. The reward is not necessarily material, but more spiritual and emotional, We should always have a grateful heart. As century old Ba Jin said, "I am a spring silkworm, and I will spin silk when I eat mulberry leaves." spring silkworm has paid and gained, but what it has gained is people's praise and admiration
Parents are the first teachers in our life. From the moment of a child's birth, his life is full of parents' endless love and blessing. Perhaps, parents can't give us a luxurious life, but they give a person an irreplaceable life
Parents hold up a sky of love for their children. When you are injured, crying, depressed and sad, you can come back here at any time and enjoy your parents' love. Being grateful to your parents, even a trivial matter, can make them feel gratified. I remember a public service advertisement broadcast by CCTV: a little boy, struggling with a basin of water, said to his mother naively: "Mom, "Wash your feet!" is such an advertisement, which is still popular today. Its emotion is moving, and I don't know how many people have been infected. Many people shed tears for it, not only for the lovely boy, but also for the deep love and heartfelt gratitude to their mother
Students, let's learn to be grateful to our parents! Treat our parents with a grateful heart and communicate with them with a sincere heart. Don't take our parents for granted to help us do anything. They bring us to this beautiful world, which is great enough and bring us up. They pay for us silently without asking for any return, Let's not blindly ask for their pay, learn to be grateful, with a grateful heart, to be grateful to parents!

For example, if I am grateful for nature's water, I will say thank you every time I use it. Thank you for helping me clean the stains on my body. As soon as I wash my hands, I have to say thank you every time. Is that Thanksgiving? Can the water sense my gratitude? Do I have to say it every time? Thank you practice. More examples. I say thank you all day long. If the water is human, the water will be tired of listening, If you're tired, it's no use to be grateful

Gratitude is a state of mind. It's not what you say, it's real gratitude. Everything is made by heart. Let it be and never be persistent
If you let others worry because of your gratitude, you don't have to do it. Gratitude is better than everything. Amitabha!
