Where to find formula in site

[Tknull]

I have a Drupal based site. How/where do I look in the website files to locate the formula that was coded to calculate delivery price for my business? There are sooo many files! I want to be able to tweak it if needed, as well as to give a copy of this formula to someone to use for an iOS app idea I have.
Thanks...

Probably code tied to a model (business logic) or could be pulled from a web service. Ask the developer how they did this, though I'd suggest you avoid tinkering around with a large framework's code base as one typo can bring your entire site down.

If you must, start reading the online Drupal documentation, copy site to folder on your local and do a site wide search for ship/shipping ect... There should be some vars, methods or classes with the word ship in it. Though I'd suggest your ask a Drupal expert first before making reckless changes.
