    1. The problem statement, all variables and given/known data

    The count in a bateria culture was 200 after 15 minutes and 1500 after 40 minutes.

    Find the population after 120 minutes.

    2. Relevant equations

    A=Pe^(rt)

    3. The attempt at a solution

    I did
    P=60e^(.0806 x 120)
    P= 952023.0848 (answer is wrong)

    Your form also doesn't give quite the right answer for t=15 or t=40. I think you might want to keep more decimal points before rounding off.
