Statistics indicate that the world population since world war II has been growing exponentially. If we assume exponential growth, the world population can be modeled by P (t) = 5(1.051) where P(t) is the world population in billions and t is the time in years since 1985. When (which year) will the population reach 15 billion? Round to the nearest year. {your final answer will be number only}
