The world’s population is expected to grow at a rate of 1.3% per year until at least the year 2020. In 1994 the total population of the world was about 5,642,000,000 people. Use the formula Pn=P₀e^in to predict the world’s population Pn , n years after 1994, with P₀ equal to the population in 1994 and i equal to the expected growth rate. What is the world’s predicted population in the year 2020, rounded to the nearest million?
( the ₀ is supposed to be a little zero)
