APPLICATIONS OF PERCENTAGE.

226. Percentage, or the method of reckoning by hundredths, is applied to various calculations in the practical concerns of life. Among the most important of these are Commission, Brokerage, the Rise and Fall of Stocks, Interest, Discount, Insurance, Profit and Loss, Duties, and Taxes. Its principles, therefore, should be thoroughly understood by every scholar.

Quest.-226. To what are the principles of percentage applied ? What are some of the most important of these calculations ?

COMMISSION, BROKERAGE, AND STOCKS. 227. Commission is the per cent. or sum charged by agents for their services in buying and selling goods, or transacting other business.

Obs. An agent who buys and sells goods, &c. for another, is called a Commission Merchant, a Factor, or Correspondent.

228. Brokerage is the per cent. or sum charged by money dealers, called Brokers, for negotiating Bills of Exchange, and other monetary operations, and is of the same nature as Commission.

229. By the term Stocks, is meant the Capital of monied institutions, as incorporated Banks, Manufactories, Railroad and Insurance Companies ; also, the funds of Government, State Bonds, &c.

Oes. Stocks are usually divided into portions of $100 each, called shares; and the owners of these shares are called Stockholders.

230. The original cost or valuation of a share is called its nominal, or par value ; the sum for which it can be sold, is its real value, which varies at different times.

Obs. 1. The rise or fall of Stocks is reckoned at a certain per cent. of its par value. The term par is a Latin word, which signifies equal, or a state of equality.

2. When stocks sell for their original cost or valuation, they are said to be at par ; when they sell for more than cost, they are said to be above par, or at un advance; when they do not sell at cost, they are then said to be below par, or at a discount.

3. Persons who deal in Stocks are usually called Stock-Brokers, or Stock-Jobbers.
