Question 890299: The dean of the graduate school reported that there was an average of 27 students in each classroom. Then, 56 students enrolled in the school, making a new total of 704 students. How many classrooms were there?

56 students enrolled in the school, making a new total of 704 students.

Therefore, before those 56 students enrolled, there were 704-56 = 648 students. 

Let N = the number of classrooms

Before those 56 enrolled,

there was an average of 27 students in each classroom

Therefore



Multiply both sides of the equation by N



Divide both sides of the equation by 27



There were 24 classrooms.
