11. The population of a region is growing exponentially. There were 30 million people in 1950 (when t=0) and 80 million people in 1970. (a) Find an exponential model for the population (in millions of people) at any time t, in years after 1950. (b) What population do you predict for the year 2015? (c) What is the doubling time (the time it takes for a population to double in size)?
