Question

The population of a certain animal species decreases at a rate of 3% per year. You have counted 80 of the animals in the habitat you are studying. Write a function that models the change in the animal population.

A: f(x) = 80(3)^x

B: f(x) = 80(.03)^x

C: f(x) = 80(.97)^x

D: f(x) = 80(1.03)^x

Answer 1

C. f(x) = 80(.97)^x

Explanation:

If the population decreases by 3% each year, then it would be the same as multiplying it by 97% or 0.97 each year.
