To find the total number of students at McCord Middle School, we can set up the equation based on the information given.
Let \( x \) be the total number of students.
We know that 60% of the total student body equals 300 students. This can be expressed mathematically as:
\[ 0.60x = 300 \]
To solve for \( x \), divide both sides by 0.60:
\[ x = \frac{300}{0.60} \]
Calculating that gives:
\[ x = 500 \]
So, the total number of students at McCord Middle School is 500 students.
