??? 70 comma 000 ??? are you kidding me? Why not type 70,000?
Anyway, since the population doubles every 28 months, then after x months,
P(x) = 70000 * 2^(x/28)
So, now just plug in x=48, which is how many months in 4 years, right?
The population of a southern city follows the exponential law. If the population doubled in size over 28 months and the current population is 70 comma 000, what will the population be 4 years from now?
