The population of a certain inner-city area is estimated to be declining according to the model P(t)=466,000e^(−0.018t), where t is the number of years from the present. What does this model predict the population will be in 12 years? Round to the nearest person.

To find the prediction of the model we need to substitute t = 12 into the equation as follows:


\begin{gathered} P(t)=466,000\cdot e^(-0.018\cdot12) \\ P(t)=466,000\cdot e^(-0.216) \\ P(t)=375,473 \end{gathered}

According to this model, the population will be 375,473 people.
