Answer:
75%
Step-by-step explanation:
Given the following;
Number of student at the beginning = 18 students
Number of students at the end = 24 students
Increase in number of student = 24 - 18
Increase in number of student = 6
% increase = Increment/Number at the begining * 100
% increase = 6/18 * 100
% increase = 600/8
% increase = 75%
