The number of sixth-graders expected next year is 376.
This is 40% of the expected school enrollment.
We can write this as an equation:
0.40 * E = 376
To find the expected school enrollment E, we can divide both sides of the equation by 0.40:
E = 376 / 0.40
E = 940
Therefore, the expected school enrollment next year is 940 students.
Now we write out the argument and find the final answer.
Let x be the total number of students expected to enroll next year.
We are given that 376 students are sixth-graders, and this represents 40% of the total enrollment.
We can set up the equation:
0.40x = 376
To solve for x, we divide both sides by 0.40:
x = 376 / 0.40
x = 940
Therefore, the expected total enrollment for next year is 940 students.
Final Answer: The final answer is $\boxed{940}$
