Question

A town has a population of 140,000 and grows at 3% every year. What will be the population after 14 years,to the nearest whole number?

Answer 1

Take the population currently - 140,000
Multiply it by 3% growth
then multiply it by the 14 , because that is the time it will be growing
and you will get
2.43498491813e+23
in your calculator

Answer 2

`\bf \qquad \textit{Amount for Exponential Growth}\\\\ A=I(1 + r)^t\qquad \begin{cases} A=\textit{accumulated amount}\\ I=\textit{initial amount}\to &140000\\ r=rate\to 3\%\to (3)/(100)\to &0.03\\ t=\textit{elapsed time}\to &14\\ \end{cases} \\\\\\ A=140000(1+0.03)^(14)\implies A=140000(1.03)^(14)`
