The population of a region is growing exponentially. There were 20 million people in 1980 (when t=0) and 55 million people in 1990. Find an exponential model for the population (in millions of people) at any time t, in years after 1980. P(t)= What population do you predict for the year 2000? Predicted population in the year 2000 = million people. What is the doubling time? Doubling time = years.
