    Well, how to solve for R.

    I knows its pretty straight forward, I just cant remember



    1.68/(r-0.085) = 73

    What is R? How do I calculate it?

    Multiply both sides of the equation by (r-0.085) and divide both sides by 73 (this is called cross multiplication), you'll end up with 1.68/73 = r - 0.085.
    Can you take the last step yourself?
    (We tend not to fully answer questions here, to both discourage homework requests and to encourage some self-help with a few pointers given).

    Post back if you're still stuck.
