Question

Terry’s 7th grade class started out with 40 students. Over the last 4 months the class has seen a 30% decrease in students. How many students are now in Terry’s class?

Answer 1

Answer:

28 students

Step-by-step explanation:

30% is equal to .3

40 x .3 equals 12

This means the class has lost 12 students.

40 - 12 is 28.

Another way:

Because the class has lost 30% of it's students, you know that the class is 70% of it's original capacity.

70% is equal to .7

40 x .7 is 28
