126 students in the fourth grade went on a spring outing, how to rent a car and there are no vacanci

Solution: Set up a limit of 38 people in the passenger car x, limited to 12 people in the passenger car y, from the title:

38x+12y=126, because there are no vacancies and the number of cars is an integer, therefore:

x=3，y=1．

A: Rent 3 buses for 38 people and 1 bus for 12 people.

126 38 = 3 cars. 12 people.

12 12 = 1 car.

So 3 cars with a seating limit of 38 people and a car with a seating capacity of 12 people are fine.

126 students went on a spring outing, why are there no vacant seats?

Answer: 3x38 12 126 (name).

3 buses and 1 van.

126 38 = 3 cars. 12 (person).

12 people can be seated in one car.

3 1 = 4 (vehicles).

A: It is possible to rent 3 cars for 38 people and 1 car for 12 people.

126 divided by 38 = 3... 12

3 cars for 38 people, one car for 12 people.

3 coaches (38 people), 1 minibus (12 people).

Use the enumeration method. 3 large cars, 1 small car. 38 3 12 1 = 126 (person).

Use a list to do the math. Soon.

Dried tofu, dried tofu, dried tofu, dried tofu, dried tofu.

There are 199 people in the fourth grade who go on a spring outing, and each car can seat 20 people, and 10 cars have to be rented.

According to the question of the source of the ear, the state clan quarrel style:

9 and 19 20

So to rent 10 cars.

Nature of division calculations:

The dividend expands (shrinks) n times, and the divisor does not change, and the quotient expands (shrinks) n times accordingly. The divisor expands (shrinks) n times, and the dividend remains unchanged, and the quotient shrinks (expands) n times accordingly.

Formula: Divisor Divisor = Quotient; Dividend quotient = divisor; Quotient divisor = dividend; Case with remainder: Dividend Divisor = quotient ......Remainder (where the remainder is less than the divisor), divisor quotient + remainder = dividend.

Considering that division and multiplication are inverse operations of each other, and the meaning of multiplication is a simple operation to find the sum of multiple identical additions, this situation can also be explained as follows: the dividend's subtraction is constantly subtracted until the remainder value is lower than the number of exclusions. For example:

17÷5=3…2, i.e. 17 minus 3 5s, leaving 2.

Since the number of passengers limited by large and small cars is different, in order to save the most money, it is necessary to give preference to large vehicles with a large number of passengers. First of all, we calculate how many carts are needed: 192 45 = 4 and 12, that is, at least 4 carts are needed.

Then calculate how many cars are needed: 12 30=, rounded up to 1, i.e. 1 car is needed. Therefore, a total of 4+1=5 cars need to be rented.

We chose to rent 4 large cars, 1 small car plan, so the total car rental cost to pay is: 4 900 yuan (each large car rental) + 1 660 yuan (each small car rental) = 3960 yuan Therefore, renting 4 large cars and 1 small car is the most economical, you need to pay 3960 yuan for the rental cost <>

The fourth grade organized a spring outing, 3 teachers took 192 students to participate in the Danga activity, how to rent a car to save the most money, need to sell more and sell a lot of money?

Since the number of passengers limited by large and small cars is different, in order to save the most money, it is necessary to give preference to large vehicles with a large number of passengers. First of all, we calculated how many big cars we needed: 192 45 = 4 and 12, that is, at least 4 big cars are needed.

Then calculate how many small cars are needed: 12 30=, rounded up to 1, that is, 1 car is needed. Therefore, a total of 4+1=5 cars need to be rented.

We chose to rent 4 large cars, 1 small car plan, so the total car rental cost to pay is: 4 900 yuan (each large car rental) + 1 660 yuan (each small car rental) = 3960 yuan Therefore, renting 4 large cars and 1 small car is the most economical, you need to pay 3960 yuan for the rental cost <>

Summary. Hello dear<>

According to the information given in the title, we need to rent a car for 46 people to go on a spring outing, and there are two options to choose from. The first option is to rent a car, each car can seat 5 people, and the rent is 26 yuan; The second option is to rent a bus, each car can seat 30 people, and the rent is 480 yuan. Which option is better?

Start by calculating how many cars it will take to fit everyone. For option 1, 9 cars are needed (46 5=, rounded up to 9); For option 2, only 1 bus is needed. Then calculate the cost of renting a car.

For option 1, 9 cars are needed, and the total rent to be paid is: 9 26 = 234 yuan; For option 2, only 1 bus is needed, and the total rental fee to be paid is: 480 yuan.

To sum up, renting a coach is a better option to meet everyone's needs and save money on renting a car.

There are 46 people in the fourth grade who go on a spring outing, and there are the following two car rental plans, plan one: 5 cars, 26 yuan to rent one.

According to the information given in the title, we need to rent a car for 46 people to go on a spring outing, and there are two options to choose from. The first option is to rent a car, each car can seat 5 people, and the rent is 26 yuan; The second option is to rent a bus, each car can seat 30 people, and the rent is 480 yuan. Which option is better?

First, calculate how many cars it will take to fit everyone. For option 1, 9 cars are needed (46 5=, rounded up to 9); For the second option, only 1 bus is needed to balance the cherry blossoms. Then calculate the cost of renting a car.

For option 1, 9 cars are needed, and the total rent to be paid is: 9 26 = 234 yuan; For option 2, only 1 bus is needed, and the total rental fee to be paid is: 480 yuan.

To sum up, renting a coach is a better option to meet everyone's needs and save money on car rental costs.

In fact, in reality, Wang Ye also needs to consider other aspects of the cause, such as road conditions and traffic congestion. If the roads are in good condition and traffic is clear, a car is also a good option to save money on rentals and increase opportunities for interaction with your peers. However, if the road conditions are poor or the traffic is congested, renting a bus can better ensure the safety and comfort of travel.

Therefore, when making a decision, you need to consider it comprehensively according to the actual situation and weigh the pros and cons of Yuling shirts.

Need to rent 7 cars.

According to the data of the mathematical equation solution, a total of 263 people went to the spring outing, 38 people had a car, and dividing 263 by 38 equaled 7, so a total of 263 teachers and students in the fourth grade went to the spring outing, and each car is now 38 people, and 7 cars need to be rented.

Spring outing, known as stepping on the Qing in ancient times, is an ancient Han folk cultural and sports activity, which was generally in the Shangsi Festival and the Qingming Festival in ancient times. On March 3, the weather was new, and there were many beautiful people on the waterside of Chang'an.

120 30 = 4 yuan.

150 45 = yuan.

The per capita fare of a large car is lower than that of a small car. So try to rent a big car.

In the case of ensuring that there is no vacancy in the car, the maximum number of large cars can be rented is 3.

The car is: (195-3*45) 30 = 2 cars.

Fare: 150*3+120*2=690 yuan. Lowest rent.

Verification: If there are 2 large cars, the small cars are (195-45*2) 30=3....15, 4 cars are needed.

The fare is: 150 * 2 + 120 * 4 = 300 + 480 = 780 yuan.

If there is 1 large car, the small car is (195-45*1) 30=5, and the fee for 5 small cars is 150*1+120*5=150+600=750 yuan.

So there are 3 large cars and 2 small cars, and the rent is the lowest.

It should be 280 8 288 (people).

288 42 6 (vehicles) ......36 (person).

6+1 7 (cars).

7 420 2940 (yuan).

288 18 16 (vehicles).

16 200 3200 (yuan).

420 6+200 2 2920 (yuan).

A: Renting a car costs at least 2,920 yuan.

It's just my idea, but I'm not sure if it's right.

Wrong, please forgive me. By the way, I'm blessed with a great life.

280 ten 8 = 288 (person).

288 42 = 6 (vehicles), remaining 36 (people) need to rent 7 cars, 7x420 = 2940 (yuan).

288 18 16 (vehicles).

16x200=3200 (yuan).

If you rent 6 cars for 42 people and 2 cars for 36 people and 18 people for the remaining 36 people, you should pay the car rental fee:

420x6+200x2=2920 (yuan).

If you're not sure, don't say it (the answer is wrong).

Solution: Tong and there is a rotten wheel ruler for X cars.

40x+20=45（x-1)-10

40x+20=45x-45-10

40x+20=45x-55

45x-40x=20+55

5x=75x=15

There are 40 x + 20 = 40 15 + 20 = 620 people.

Set the number of vehicles as a and the number of students as b, 40a+20=b; 45*（a-2）+10=b；Synthesically, a=20, b=820That is, there are 20 cars, and 820 students are rented and demolished.

There are a total of x cars, and the rough land y name is a student.

40x=y-20

45x=y+10

x=6 y=220

There are 6 cars and 220 students.

There are a total of x cars in the tour core, and the number of students remains the same.

40x+20=45(x-1)

x = 15 students with 620 students.

After learning the binary one-time rapid trembling equation, is it a mu failure?

There are x vehicles, and there are Y classmates. Column equations have.

40x+20=y

45(x-2)+35=y

The solution is x=15 and y=620

According to the title, the cheapest rental car should be when every space is as full as possible, and there are no or few empty seats is the most cost-effective. And it will be cost-effective to get as big as possible, because the unit price of a large car is relatively low. The unit price of the large car is 520 40 = 13 (yuan) and the unit price of the small car is 450 30 = 15 (yuan).

In total, there are 12 + 172 = 184 (people).

184 40 = 4 (vehicles) ......24 (person).

Option 1: 5 large vehicles.

5*520=2600 (yuan).

Scheme 2: 4 large cars, 1 small car.

2530 (yuan).

Scheme 3: 3 large cars and 3 small cars.

2910 (yuan).

The rest of the plan is mostly small cars, which is not cost-effective, so we will not continue to calculate. Among the existing schemes, it is obvious that option 2 is the most cost-effective, with 4 large cars and 1 small car.
