Price = 0.1e^(x) (X is the number of sold tiles in 100,000s)

On the 11th of January the number of sold tiles was 591.659, this means that the current price per tile at that moment was

0.1e^(5.91659) = 36.77 ($)

So now we can calculated the amount of tiles that needs to be sold to reach $100 a tile!
