Question

The population of Bridgeville, PA, is 5,300 with a growth rate of 1.3% per year. Which expression could be used to estimate the population of Bridgeville t years from now?

Answer 1

`PA=5300(1+1.3)^t`

However, this equation does not take into account the death rate.

Explanation:

Let population be PA

Use the same equation they use to calculate compound interest

Principle sum is what you start with:`->P`

So we have: `->P(1+1.3/100)^t`

But `P=5300` giving:

`PA=5300(1+1.3)^t`
