In a school with 5 classes, each class has 2 students less than the previous class. How many students are there in the largest class if the total number of students at school is 100?  Choose the correct choice from the following choices:
A) 24
B) 25
C) 26
D) 27
E) 28
Let x be the number of students in the largest class.   Then x + (x-2) + (x-4) + (x-6) + (x-8) = 100   5x -20 = 100   5x = 120   x = 24   The answer is 24.
