A country's population in 1992 was 72 million. In 1998 it was 76 million. Estimate the population in 2012 using the exponential
ella [17]
Your exponential growth formula, P(t) = A e^(kt), contains two unknown constants, A and k. Once you find them, you can find the population for any t. (I assume, t is measured in years.) From your "story", you have: 

<span>72 million = P(1992) = A e^(1992 k) </span>
<span>76 million = P(1998) = A e^(1998 k) </span>

<span>From these two equations, you can find the two unknowns A and k (do it yourself). Once you do, your answer is </span>

<span>P(2012) = A e^(2012 k)</span>
