1. The problem statement, all variables and given/known data The average growth rate of the population of a certain city is 7.5% per year. The city's population is now 22,750 people. What is the expected population in 10 years? 2. Relevant equations I was always taught this formula for exponential growth N(t) = N_0 e^(kt) N = population N_0 = population at t(0) e = 2.7... k = some positive constant t = time Here's what my teacher wrote on my paper for the formula f(x) = C(1 + r)^x f(x) = population C = initial population r = growth rate 3. The attempt at a solution no i dont understand how to do this exactly because I don't know what to use for the constant k so i used the second one 22750 (1 + .075)^10 = 46888.4680 now what I don't udnerstand is that this really makes no sense at all becasue if I wanted to fidn the population at 10 minutes or ten centuries and just plugged in 10 into the equation with no units at all I would get the same exact answer. Can youp please tell me how to go about reasoning this out... THANKS!
