Solving the Mystery of Così Middle School's Student Population

In a recent development, it has been reported that 80 students from Così middle school rode bicycles to school, which accounts for 40% of the total student population. As a math enthusiast, you might be curious to know the total number of students attending Così middle school. In this article, we will delve into the world of mathematics and solve this intriguing problem.

To find the total number of students attending Così middle school, we need to use the concept of percentages. The given information states that 80 students represent 40% of the total student population. We can use this information to set up an equation and solve for the unknown variable, which is the total number of students.

Let's denote the total number of students as 'x'. Since 80 students represent 40% of the total student population, we can set up the following equation:

80 = (40/100) × x

To simplify the equation, we can multiply both sides by 100 to get rid of the fraction:

8000 = 40x

Now, we can solve for x by dividing both sides of the equation by 40:

x = 8000 ÷ 40

x = 200

Therefore, the total number of students attending Così middle school is 200. This means that 80 students, who rode bicycles to school, represent 40% of the total student population. We hope this article has provided you with a clear understanding of how to solve this problem using mathematical concepts.

This problem may seem trivial, but it has real-world applications in various fields, such as:
