Question: A pharmaceutical company distributed 12000 trial samples of an acne relief cream to middle school students. How many middle class students were there in the school, if each student received 4 samples?


A ) 3100
B ) 3000
C ) 2700
D ) 3200

Steps to derive

1 Let s be the number of students in the school.

 [Write an equation.]
2 s x 4 = 12000

 [Divide each side by 4.]
3 (sx4)4 = 120004

 [Simplify.]
4 s = 3000

5 There were 3000 students in the school.
