How much is minecraft one a pc? In America. If that even makes a difference?

$26.95

In the US, the PC version of Minecraft is $27 for one copy. IF you buy the prepaid card (which includes a redemption code) from a store (like GameStop, Best Buy or Walmart), you can find 2-pack (2 copies) for $50 for a slight discount (saving $4 overall).

Please be aware that I'm rounding up to the next dollar to keep figures simple.
