Thank you to both of you, Marg1e and salmonmac for your replies! I'm definitely grateful for any and all help!
I'm actually not a math major, I have degrees in Finance, German and Judaic Studies -- so I guess it might be the finance part of me that fell into a weird set of formulaic calculations. (which, especially for me, is rather unusual!)
I appreciate the graph paper and I'll go ahead and try to chart that out and let you know if I have any luck.
All the best always,
