A population numbers 11,000 organisms initially and grows by 12.4% each year. Suppose P represents population and t represents the number of years of growth. An exponential model for the population can be written in the form

Question

P=ab^t , where P=

Answer 1

P = 11000(1.124)^t

Answer 2

How did you get 1.124?

Answer 3

12.4% = .124
100% = 1
so if something increases by 12.4% we end up with
100$ + 12.4% = 112.4% = 1.124
