The population of a certain animal species you are studying decreases at a rate of 3.5% per year. Only 80 of the animals in the habitat remain after 3 years of conducting your research. What was the initial amount of animals
The function: f ( x ) = x * 0.965^t where x is the initial amount and t is the number of the years 80 = x * 0.965^3 80 = x * 0.89632 x = 80 : 0.89632 ≈ 89 Answer: The initial amount of animals was 89.
