    Answer:

    Number of students= 820.64 = 821

    Step-by-step explanation:

    Giving the following information:

    Current attendance= 950 students

    Number of periods= 3 years

    Decrease rate= 5%

    To calculate the number of students in attendance in 3 years, we need to use the following formula:

    Number of students= current attendance*(1+decrease rate)^(-n)

    Number of students= 950*(1.05^-3)

    Number of students= 820.64 = 821
