=====================================================

Introduction

In this problem, we are given a school bus with 22 rows of seats, and each row can accommodate 4 students. The students have filled 19 rows of seats and half of the remaining seats. We need to find out how many seats on the bus are empty.

Calculating Total Seats

To start solving this problem, we first need to calculate the total number of seats on the bus. Since there are 22 rows of seats, and each row can accommodate 4 students, the total number of seats can be calculated as follows:

Total\ seats = 22 \times 4 = 88

Calculating Filled Seats

Next, we need to calculate the number of seats that are filled by the students. We are given that 19 rows of seats are filled, and each row can accommodate 4 students. Therefore, the number of filled seats can be calculated as follows:

Filled\ seats = 19 \times 4 = 76

Calculating Remaining Seats

Now, we need to calculate the number of remaining seats on the bus. Since there are 88 total seats and 76 filled seats, the number of remaining seats can be calculated as follows:

Remaining\ seats = 88 - 76 = 12

Calculating Occupied Remaining Seats

We are given that half of the remaining seats are occupied by students. Therefore, the number of occupied remaining seats can be calculated as follows:

Occupied\ remaining\ seats = \frac{1}{2} \times 12 = 6

Calculating Empty Seats

Finally, we can calculate the number of empty seats on the bus by subtracting the occupied remaining seats from the remaining seats:

Empty\ seats = 12 - 6 = 6

Conclusion

In this problem, we calculated the total number of seats on the bus, the number of filled seats, the number of remaining seats, the number of occupied remaining seats, and finally, the number of empty seats. We found that there are 6 empty seats on the bus.

Discussion

This problem involves basic arithmetic operations such as multiplication, subtraction, and division. It also involves understanding the concept of fractions and percentages. The problem requires the student to break down the problem into smaller steps, calculate the values, and finally, arrive at the solution.

Real-World Applications

This problem has real-world applications in various fields such as transportation, logistics, and management. For example, in a school bus, the driver needs to know the number of empty seats to ensure that there is enough space for all the students. Similarly, in a logistics company, the manager needs to know the number of empty seats in a truck to plan the transportation of goods.

Tips and Tricks

To solve this problem, the student needs to follow the order of operations (PEMDAS) and break down the problem into smaller steps. The student should also use visual aids such as diagrams or charts to help them understand the problem better.

Practice Problems

Here are some practice problems that the student can try to solve:

A school bus has 25 rows of seats, and each row can accommodate 5 students. If 20 rows of seats are filled, how many seats are empty?
A truck has 30 seats, and each seat can accommodate 2 boxes. If 20 seats are filled, how many boxes can be transported?
A school has 20 classrooms, and each classroom can accommodate 30 students. If 15 classrooms are filled, how many students are in the school?

Solutions

Here are the solutions to the practice problems:

A school bus has 25 rows of seats, and each row can accommodate 5 students. If 20 rows of seats are filled, how many seats are empty?

Total\ seats = 25 \times 5 = 125 Filled\ seats = 20 \times 5 = 100 Remaining\ seats = 125 - 100 = 25 Empty\ seats = 25


*   A truck has 30 seats, and each seat can accommodate 2 boxes. If 20 seats are filled, how many boxes can be transported?
```math

Total\ boxes = 30 \times 2 = 60
Filled\ seats = 20
Filled\ boxes = 20 \times 2 = 40
Remaining\ boxes = 60 - 40 = 20

A school has 20 classrooms, and each classroom can accommodate 30 students. If 15 classrooms are filled, how many students are in the school?

Total\ students = 20 \times 30 = 600 Filled\ classrooms = 15 Filled\ students = 15 \times 30 = 450 Remaining\ students = 600 - 450 = 150
