A report tells us that in 2019 there were 800 of a certain type of animal in an area, but that the population decreased by 4% that year. For purposes of this problem we assume that this 4% annual rate of decrease continues. a) Find an exponential model that gives the animal population S as a function of t in years since 2019. S = b) How long will it take this population to reach 600? (Round your answers to two decimal places.) years after 2019
