NikAS [45]

Answer:

The number of enrollments increased by 5%.

Step-by-step explanation:

Given that:

Number of students at the beginning of the year = 480

Number of students at the end of the year = 504

Change = 504 - 480 = 24

This indicates increase.

Percent of change = $\frac{Change}{Old\ number\ of\ students}*100$

Percent of change = $\frac{24}{480}*100$

Percent of change = 5%

Hence,

The number of enrollments increased by 5%.
