Efficiency = input / output If expenses are $60 and revenue is $80 (perhaps net of interest revenue/expense) the efficiency ratio is 0.75 or 75% (60/80) â meaning that $0.75 are spent for every dollar earned in revenue.
As mentioned above a true antique is more than 100 years old, but some stores value furniture older than 50 years as antique and fine antique dealers will label items antique if they are more than 150 years old. The best way to find out is get the exact age of the piece.
If you use the term on Ebay, you can mean a particular decade, like Vintage 1970s or Vintage 1940s.. I does not refer to a particular date. Most real dealers will agree that to be an antique, the item must be 100 years or older. I get annoyed when I'm looking for something antique and I get a gazillion hits on antique finish stuff.
