Katarina [22]

Answer:

The number of student increased each year by 986.58.

Step-by-step explanation:

Given : In 2002, there were 972 students enrolled at Oakview High School.

To find : The number of students has increased by 1.5% each year ?

Solution :

Using the exponential growth function,

P(t)=P_o(1+r)^t

Here, P_o=972 is the initial population

r=1.5%=0.015 is the rate

t=1 time

P(t)=972(1+0.015)^1

P(t)=972(1.015)

P(t)=986.58

i.e. the number of student increased each year by 986.58.
