can someone help me

Question

In a town whose population is 3000, a disease creates an epidemic. The number N of people infected t days after the disease has begun is given by the function N(t) = 300/1+21.5*e^-0.5t . Find the number infected after 8 days.

Answer 1

Note:  you need to use parentheses!

 

N(t) = 3000/(1+21.5e^-0.5t)

 

N(8) = 3000/(1+21.5e^-4) ≈ 2152

 

NOTE:  In my original answer, I typed 215 instead of 21.5.  Also, the number 300 in your formula should be 3000 (the initial population).  I believe that my new answer is now correct.
