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!

you have to evaluate e^(-5) can be done, by this method (1/e)(1/e)(1/e)(1/e)(1/e) That would be fun multiplying without a calculator.
