Well that sucks. Following that equation:

There are 69,000 people within 3 miles of my proposed site. The nearest theaters are about 6 miles away, so I will assume that within the 3 miles, they might come to me.

I estimate maybe 80% of them go to the movies (the average HH income is $114k), so that gives us 55,200 people.

Times two is 110,400.

I'll skip the dividing by screen, since they'll be my screens.

30% of them will buy concessions, so thats 33,120, at three dollars a pop is $99,360.

I mean, even assuming you'll make $2.50 a ticket, thats $220,800 in ticket sales. That's a total of $320,160.

I mean it's not that bad, but how does one go about paying off investment if building the cinema takes $950k?
