    Isn't the point what are your numbers?

    I'm not thinking the solution of another problem is going to need much help.

    I'm not catching your point. I posted the solution to the same question but with different values to make it easier for people to determine the final answer to my values. If you can help then I'll be glad, if not then please ignore this thread. Thank you.
