replace t with 5 and evaluate using your calculator

(I got 6215)

I was the population to increase in a new development.

Are you sure your formula is correct?

6215 is the right answer. What were the steps without a calculator? Thanks!

To evaluate e^(-.15) without a calculator would be beyond the scope of most of today's college students.
