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.
Even if they may not be aware of what the standard is, many people realize that there is some standard for defining an antique. Many people speculate that if an item is not antique it must be at least be vintage.. Sometimes this is the case, but not always. Often, it is all in the wording.
