You can find the size of a population after t years using the formula N = No(1 + r)t where No is the initial size of the population, N is the final size of the population, r is the rate of growth or decay per time period, and t is the number of time periods.
Just over 1 million prisoners (actually 1,080,000) were in the United States in 1995. Assume that the growth rate, r, is the same for the general population at 76% per 15 years. In which year would you expect the number of prisoners to double?
Don't know how to set this up to solve.

Anonymous,
messed up the formula
N = No(1 + r)^t
