INTEREST. 1 INTEREST is of two kinds; Simple and Compound 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, 6l. for the use of 100l. 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, 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. EXAMPLES. 1. What is the interest of 391. 118. 8d. for one year at 61. per cent. per annum ? £. s. d. 6 0/12 Ans. £27s. 6d. 2. What is the interest of 2561. 10s. 4d. for a year, per cent. ? Ans. 11 169. Galin 3.

What is the interest of 468 dols. 45 cts. for one year at 6 $ cts. 468, 45 6 28|10, 70-$28, 10cts. 7m. Ans. Here I cut off the two right hand integers, which di vide by 100 but to divide federal money by 100, you need only call the dollars so many cents, and the inferior denominations 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. Required the interest of 135 dols. 25 cts. for a year at 6 per cent. 8 cts. 135, 25 6 811, 508, 11cts. 5m. Ans. 7.

Ans. 2616ets.$26, 16ets. ANOTHER METHOD. Write down the given principal in cents, which multiply by the rate, and divide by 100 as before, and you will. have the interest for a year, in cents, and decimals of a cent, as follows: 9. What is the interest of 875, 65 cents for a year, at per cent. ? 6 Principal 7565 cents. Ans. 441,90cts.=44133⁄4cts. or $4, 41ets. 9m. 10.

To find the simple interest of any GENERAL RULE. 1st. Find the interest of the given sum for one year. 20. Multiply the interest of one year by the given number of years, and the product will be the answer for that time. Sd. If there be parts of a year, as months and days, work for the months by the aliquot parts of a year, and for the days by the Role of Three Direct, or by allowing 30 days to the month, and taking aliquot parts of the same. * By allowing the month to be 80 days, and taking aliquot parts thereof, you will have the interest of ar y ordinary sum sufliciently exact for common use; but if the sum be very large, you may say, As 360 days is to the interest of one year eriven number of days: to the interest required. so is the |
