Math Attack

I've never been a big math fan myself. I always did better in English and Science as they are more interesting subjects to me, but strangely enough I never realized how closely related some math questions were to those subjects. For instance:

"If one typist can type 1 page in 3 minutes, how many typists would it take to type 36 pages in 5 minutes?"

Of this question I remember thinking to myself... 'who the hell cares?'

Now that I'm "all grown up" I find myself in a funny situation to actually caring. I'm in the process of putting together a business proposal/plan to submit to an investor so I can possibly start a new small business in the writing industry. Ultimately, I've actually had to do the math in that above, dreaded, question since it does apply to my business proposition.

Question: How does your K-12 education affect your writing today, be it career or hobby writing?
