    A is going to be the amount remaining, and it will be our variable. The equation is already solved for A, which is good. You say that you are getting stuck, so I assume that you have an answer to this problem to serve as reference?

    I do not know the answer exactly, your variables seem accurate. Perhaps you evaluating it wrong, seeing as your setup is correct. Also, please be patient in waiting for replies because I am operating on a slower internet connection but I am working to help you as fast as I can.

    I would go with A. What answer were you obtaining so we can identify your error?

    A=Pe^-rt P=26600 r=0.029 t=10 A = amount remaining after t time. -r is your rate of decay, and since our population is decreasing, we have -r. t is the time your rate of decay is applied for. Make sure that r and t are the same unit; since t is years and r is %/year, we are ok to start evaluating. \[A=Pe^{-rt}\]\[A=29,660e^{-(0.029)(10)}\]\[A=22,148.6=22,149\]Make sure that you are able to put this into your calculator accurately and obtain the proper answer.

    Yeah I was making that mistake too. Your original post has 29,600 as the value, but you listed 26,600 a few times. Good thing we found the error.

    is this right? The yearly attendance at a local movie theater is 68,000 and grows continuously at a rate of 3.5% each year. What is the approximate attendance at the movie theater in eight years? 89,973
