1. Let's say that at the end of 2010, the population of Athens was 100,000. Let's also say that the relative growth rate of the population was 2% per year.
What's the population at t = 0.5 years after the end of 2010?
2. To solve this sort of problem, I thought I'd have to use: y= A(1+b)t
A is the initial population
b is the growth factor
t is the timeI thought that since the population growth rate was 2% per year, the growth factor would have to be (.001 + 1).
I figured out the .001 by saying: (.2%/yr) = (x/.5yr)
x= .1% or .001
(.1%/100%) = .001 = b
y= 100,000(1 + .001).5
y= (100,000)(1.001)
y= 100,100 people
Is this right?
Thanks for the help! :)
