Question

What is the rat pop in 1990?
What does the model predict the rat pop was in the year 2005?

Answer 1

Pop in 1990 = 81 million rats

Pop in 2005 = 127 million rats

Explanation:

Given the function, the population of rats in 1990 is when we replace t with "0" which strictly gives the coefficient 81 that represents 81 million rats.

The rat population in 2005 is given by the formula when t = 15

This is: approximately 127 million rats.
