Mailing lists are more expensive than that....but water varies in price from premium bottled, to store brand bottled, to tap water, to well water...Now the measurement might be pints or liters or quarts or a percentage of gallons, or even weight, but water sells at widely differing prices that fits this profile....

Hello,

I don't think they are talking about mailing lists, but rather the characters necessary to spell each number depending what their house number is.

In Aus, us rural folk have numbers that commence from the major intersections radiating from the GPO. Odd numbers on the Left, even on the right with number 100 being at 1km, 150 being 1.5km and so on, but we are encouraged to use numbers rather than spell them out. I have seen numbers in excess of 22000 on some places.

That's very interesting, I guess I missed that one....pretty random

..."What is the highest house number in the world?

But there's one more claim to fame: the world's highest street address number: 986039 Oxford-Perth Road. 986039 Oxford-Perth Road, a private residence with what is probably the highest numbered address in the world."...Jun 10, 2019

Not very relevant here where you can throw a stone and probably hit the next town center...There is actually a street here that is divided into two different towns, the odd numbers were on one side of the street going up in number then halfway through the street they switched sides and started back down, you actually had the same house number on both sides of the street across from each other at an angle...it was very confusing as there was no indication that you had passed from one town to the next, to add to the confusion this one half street was isolated from the main body of the town as an island in the middle of another town....You can imagine the difficulty in having things delivered for the unfortunate residents of this street....and how many times they have had to explain the bizarre geographical situation...

Have a look at "Binya Avenue" in Tweed heads. The houses on the North are in one state, while the sporting field in in another. Kids go interstate daily to play in the park. (Except at the moment where there is an interstate lockdown due to virus concerns.)

Or very slightly further East where the state border is the front boundary of the properties that front "Boundary Street" You go interstate every time you go out to collect the mail. Their mailboxes front Queensland while the property is actually in New South Wales.

I did a trendline in Excel with a log scale axis and got $5.22. How did you get your value?

I got 5.2166. I used the idea that the price is linear with the power of 12, so y = m x + b

y = 1.09 (exponent of 12) + 1.09

1.09 = 1.09 (0) + 1.09

2.18 = 1.09 (1) + 1.09

3.27 = 1.09 (2) + 1.09

5.2166 = 1.09 (3.7859) + 1.09

3.7859 = log 12181 / log 12

I don't know what is online that has a price quantity, maybe something based on 12?

I believe the concept of buying an abstract concept like a number is impossible.

Pretty expensive Pi!

What stumped me is that "twelve" is different than the symbols 12
