A population numbers 16,000 organisms initially and grows by 15.8% each year. (A) Suppose P represents population, and t the number of years of growth. An exponential model for the population can be written in the form P: = = a b where a 16000 and b= (B) Use logs to determine the number of years until the population reaches 64,000 organisms. Round answer to 2 decimal places. t= years
