A mathematical model for world population growth over short intervals is given by P = Poe\

A mathematical model for world population growth over short intervals is given by P = Poe , where Po is the population at time t = O, r is the continuous compound rate of growth, t is the time in years, and P is the population at time t. How long will it take the world population to triple if it continues to grow at its current continuous compound rate of 1.4% per year? Substitute the given values into the equation for the population. Express the population at time t as a function of Po. (Simplify your answers.)
