Question

Enrollment in a business class decreased from 25 to 15 students. What was the percent of decrease in enrollment?

Answer 1

Answer:

The percent of decrease in enrollment is 40 %.

Step-by-step explanation:

Given,

The initial enrollment of students = 25,

While, the new number of enrollment  = 15,

Since, initial enrollment > new number of enrollment

Thus, the enrollments are decreased

And, the total decreasing in number of enrollments =  Initial enrollments - new number of enrollments

= 25 - 15 = 10

Hence,

$\text{The percentage of decrease in enrollment} = \frac{\text{Total decreasing}}{\text{ Initial enrollment}}\times 100$

$=\frac{10}{25}\times 100$

$=\frac{1000}{25}$

$=40\%$

Answer 2

-40% was the change.
