  • algebra - ,

    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.

    5x-2y=4 m= b=

    -x+4y=12 m= b=
