Final answer:
The enrollment in the Middle School next year will be 183 students.
Step-by-step explanation:
To find the number of students enrolled in the Middle School next year, we need to increase the enrollment by 22%.
First, calculate 22% of 150, which is 0.22 x 150 = 33.
Next, add the increase to the current enrollment: 150 + 33 = 183.
So, there will be 183 students enrolled in the Middle School next year.
