Annual rate of change in the number of students in the band is 5 students per year.

Step-by-step explanation:

In 2004, there were approximately 275 students in the Delaware high school band.

Number of students in band on 2004 = 275

In 2010, that number increased to 305

Number of students in band on 2010 = 305

Duration of years = 2010 - 2004 = 6 years

Increase in number of students in band = 305 - 275 = 30

\(\\\\\texttt{Annual rate of change in the number of students in the band = }\frac{30}{6}\\\\\texttt{Annual rate of change in the number of students in the band = }5\)

Annual rate of change in the number of students in the band is 5 students per year.
