Answer 1

Given,

The total population of a city has 390,000.

Each year population grows by 3.75%.

To find: The population after 10 years.

Solution:

The population after ten years is

$\begin{gathered} 390,000\times(1+\frac{3.75}{100})^{10} \\ =390,000\times(\frac{103.75}{100})^{10} \\ =390,000\times1.0375 \\ =404,625 \end{gathered}$

Hence, the answer is 404,625.
