# Math Help - population growth

1. ## population growth

A population grows from its initial level of 22,000 at a continuous growth rate of 7.1% per year.

A) Find a formula for P(t), the population in year t.

My answer for a:
Population= 22,000e^(.017*t)

B) By what percent does the population increase each year?

Is my answer to a correct and how do I do b?

The population equation should be

$P(t) = 22000(1.071)^t$.

The population increases at a rate of 7.1% per year, so each year, the population will increase by 7.1% over its previous amount.
