Here, we want to use the exponential growth formula to estimate the 2015 population
In order to use the exponential growth formula, we have to get some of the needed points like the growth rate or constant represented by K
At any point in time, A represents the initial popultaion, which is the population in 1993, given as 204 million
P represents the population at that point in time
k is what we want to calculate
t is the difference in the number of years
Thus, for between 1993 and 2015, we have ;
