SIMPLE INTEREST. Simple 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 dol lars for one year, &c. CASE 1. EXAMPLES. 1. What is the interest of 391. 11s. 8 d. for one year af 6l. per cent. per annum ? £. s. d. 6 0/12 Ans. £2 7s.6d.fr 2.

Here I cut off the two right hand integers, which divide by 100 : but to divide federal money by 100, you need only call the dollars so many cents, and the inferior denominationis decimals of a cent, and it is done. Therefore you may multiply the principal by the rate, and place the separatrix in the product, as in multiplication of federal money, and all the figures at the left of the separatrix, will be the interest in cents, and the first figure on the right will be mills, and the others decimals of a mill, as in the following EXAMPLES. 6.
