Answer:
Number of students(n1)= 4,402
Step-by-step explanation:
Giving the following information:
Number of students= 4,512
Declining rate= 2.5%
<u>To calculate the number of students next year, we need to use the following formula:</u>
Number of students (n+x)= number of students (n0) / [(1+declining rate)^(n+x)
x= number of years
Number of students(n1)= 4,512/1.025
Number of students(n1)= 4,402
Use the quadratic formula to solve the equations . you will get the answers
X < -16 is the solution
Hope this helped
