Answer:
P = 250(1 - 0.12)^t
Step-by-step explanation:
Since it is a decrease in population, we have 1 minus the rate. Since we start out with 250, we have 250 times 1 minus the rate. Since we are dealing with annual loss, we get 250(1 - 0.12)^t.
250 - starting population
1 - rate (0.12) - decreasing rate
t - time elapsed
