I have tried numerous ways to solve

Question

The population of Sasquatch in Portage County is modeled by the function

P(t) =
150t
t + 10
, where t = 0 represents the year 1803. When were there fewer than 100 Sasquatch in the county?
before the year

Answer 1

Your equation is not quite clear, but I can guide to how to solve this problem.  Since you want the year where there were fewer than 100 sasquatch, set this parameter:

 

P(t) < 100

 

 

You will use this to set an inequality.  Once you have set the inequality, solve it for t.  Keep in mind that the value of t must be positive.  After you solved for t, add that value to 1803.
