Answer:

P(t)  =  27000 - 4*t

Step-by-step explanation:

Over a period of time, if we know the  population at certain time,  and the rate of change of the population, we can express the function describing such population by means of these two parameters  

Then:

P(t)  = P₀ + 4*t

In our case

P(t)  =  27000 - 4*t

Sign minus is for decreasing population t is in months, 4 is the rate of change and finally 27000 was population the first time Talulah counted the population
