<span>The equation yˆ=31314⋅1.06^x estimates the population of a town x years after the year 1995.
What is the estimated population of the town in the year 2000? Note that 2000 is 5 years past 1995, so x will be 5:
y (in the year 2000) = 31314*1.06^5 = 41906 (must round off to the nearest integer)</span>
