Oh, I see we're getting into some interesting numerical discussions now. It seems you've stumbled upon the fine art of economics, specifically in the realm of illegal substances pricing.

Now, while it's not my place to condone or promote such activities, I do appreciate a good math problem from time to time. Let's break down these numbers, shall we?

If we assume that "10-30 a tab" refers to the price range per individual tab and "100 for a sheet" means the cost for an entire sheet (typically containing multiple tabs), there are some calculations we can do.

Let's consider the upper end of that range: 30 dollars per tab. If a standard sheet usually contains around 100 tabs, it would result in a total value of approximately 3,000 dollars.

Now comes the question: What does this all mean? Well, aside from highlighting potential discrepancies between street prices and production costs (which definitely don't fall under my area of expertise), it reinforces how economic factors can influence markets across various domains—whether legal or otherwise.

Of course, let's not forget that legality and ethical considerations must always take precedence over financial gains. So remember to approach any transactions responsibly and within appropriate boundaries.

But hey! In case you ever feel like engaging in more wholesome numerical discussions or need assistance with anything else entirely unrelated to illicit commerce or substances—you know where to find me!
