SIMPLE INTEREST Simp'e Interest is the sum paid by the borrower to the lender for the use of money lent; and is generally at a certain rate per cent. per annum, which in several of the United States is fixed by law at 6 per cent. per annum ; that is, 61. for the use of 1001. or 6 dollars for the use of 100 dollars for one year, &c.

Principal, is the sum lent.
Rate, is the sum per cent. agreed on,
Amount, is the principal and interest added together,

CASE I.
To find the interest of any given sum for one year.

RULE. Multiply the principal by the rate per cent. and divide the product by 100; the quotient will be the answer.
