The population of city in 2009 is 100 million.  If the population of the city increases exponentially and the projected population in 2015 is 231 million, which equation describes the approximate relationship between the population of the city, P, and the number of years, t, since 2009?

• p = 100(1.15)^t

• P = 231 (1.15)^t

• P = 100(1.22)^t

• P = 231 (1.22)^t
