Verified Answer :

-40% was the change.

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,

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

\(=\frac{10}{25}\times 100\)

\(=\frac{1000}{25}\)

\(=40\%\)
