Digital TV Information:

Elementary Algebra Answer 2:

2. Consider a class which has n students. In this class, t% of the students subscribe to digital TV packages. Which of the following equations represents the number of students who do NOT subscribe to any digital TV package?

F. 100(n - t)

G. (100 - t)n ÷ 100

H. (100 - t)n ´ 100

J. (1 - t)n

K. n - t

The correct answer is G.

If t% subscribe to digital TV packages, then 100% - t% do not subscribe.

Since a percentage is any given number divided by 100, the amount (rather than the percentage) is represented by this equation:

(100% - t%) ÷ 100

This equation is then multiplied by the number of students (n) in order to determine the number of students who do not subscribe to digital TV packages:

(100 - t)n ÷ 100
