Simple Interest is the sun 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 1007. or 6 dollars for the use of 100 dol lars for one year, &c. Principal, is the sum lent. Rate, is the sum per cent. agreed on. Amort is the principal and interest added together. CASE 1. 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. 11s. 8d. for one year 67. per cent. per annum? £. s. d. 39 1181 6 237 10 3 20 750 12 603 4 0/12 Ans. £2 7s. 6d.vfr. 2. What is the interest of 2361. 10%. 4. for a year, at 6 per cent ? Ans. £ 11 16s. 6d. 3. What is the interest of 5711. 13s. 9d. for one year, at Ans. £34 6s. Old. Gl. per cent.? 4.

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 denominalions 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 federal money, and all the figures at the left of the separatrix, will be the interest in cents, and the first figure ou fe right will be mills, and the others decimals of a mill, as 1. the following EXAMPLES. 6. Required the interest of 135 dols. 25 cts. for a year at cent? per $ cts. 135, 25 6 Ans. 811, 50-$8, 11 cts. 5 m. 7.
