The 7th grade French and Spanish classes each have 26 students in them, and there are nine students in the 7th grade taking both languages. If everyone in the 7th grade is in at least one of the two language classes, how many students are taking just one of the two classes?
Choose one:
A) 26
B) 28
C) 30
D) 32
E) 34
French class + Spanish class = 52 students.   Nine students are in both classes so they were counted twice.   The number of students taking just one class is 52 - 2(9) = 34.   The answer is 34.
