This is supposed to be Black-Scholes Option Pricing Model. I tried my best
to show the formula on here and I entered the cells for the values. I need to
be able to put this in an excel but I am having trouble with the placing of
parentheses and using the right formulas. If you need more clarification the
formula let me know. I did my best with what I could do. thanks for the help
in advance
