    No one can solve it without a clue as to the force of interest. Your "assume that" doesn't seem to be followed by much.

    1) No, you don't "anti derivative" anything, since that isn't a verb. It requires an integral.

    2) I cannot see the gif you attempted to display. Can you write it out?

    Well, there you go...

    \int_{0}^{11}\left(\frac{0.0245}{1-0.007t}\right)\;dt = A

    500 \cdot e^{A}\;=\; ??

    Why are you struggling with this? Do you have enough calculus background to handle the integral? Better brush up.

    Note: You should also work on using whole words and complete sentences. That WILL improve your presentation.

    Odd. I can now see the gif. It must be a firewall thing on my other PC.
