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.
There's a difference between antique and classic, at least for old cars it is. In some states any car over 25 years old is considered an antique and will qualify for antique license plates. In other states it's 30 years. In some places 30 or 35 years old exempts the vehicle from safety inspections.
