INTEREST is the allowance given for the use of money, by the Borrower to the Lender. It is computed at so many dollars for each hundred lent for a year, (per annum) and a like proportion for a greater or less time. The highest rate is limited by our laws to 6 per. Cent. that is 6 dollars for a hundred dol. Jars, 6 cents for a hundred cents, £. 6 for a £100, &c. This is called legal interest, and is always understood when no other rate is mentioned. THERE are three things to be noticed in Interest. 2. COMPOUND INTEREST is that which arises from the interest being added to the principal and (continuing in the hands of the lender) becomes a part of the principal, at the end of each stated time of payment.

BECAUSE 7 months is not an even part of a year, take two such numbers as are even parts and which added together will make 7 (6 and 1,) 6 months is į of a year, therefore, for 6 months, divided the interest of 1 year by 2 ; again, i month is of 6 months, therefore, for 1 month, divide the interest of 6 months by 6. For the days, because 6 days is of a month, or of 30 days, therefore, for 6 days, divide the interest of 1 month by 5. Lastly add the interest of all the parts of the time together, the sum is ihe answer. 3. What is the interest of £71 78.6d. 4. What is the interest of 168. for 1 year, at 6 per cent. 8d. for 1 year?

OPERATION. fo d. 9. 71 7. 6 6 2 When the rate is 6 PERCENT, there is not, perhaps, a more concise and easy way of casting Interest, on any sum of money in Dollars, Cents, and Mills, than by the following METHOD, by 2 and } . WRITE down half the greatest even number of months for a multiplier ; if there be an odd month it must be reckoned 30 days, for which and the given days, if any, seek how many times you can have 6 in the sum of them, place the figure for a decimal at the right hand of half the even number of months, already found, by which multiply the principal ; observing in pointing off the product, to remove the decimal point or separatrix two figures from its nature al place towards the left hand, that is point off' two more places for decimals in the product, than there are decimal places in the multiplicand and multiplier counted together; then all the figures to the left hand of the point, will be dollars, and those to the right hand, dimes, cents, mills, &c. which will be the interest required. SHould there be a remainder in taking one sixth of the days, reduce it to a vulgar fraction, for which take aliquot parts of the multiplicand. Thus, If the remainder be le, divide the multiplicand by 6 . 2 by 3 3If by 3 twice, If by 2 and 3. The quotients which in this way occur, must be added to the product of the principal multiplied by half the months, &c. the sum thus produced, will be the interest required. When there are days, but a less number than 6, so that 6 cannot be contained in them, put a cypher in place of the decimal at the right hand of the months: then proceed in all respects as above directed. Note. In casting interest, each month is reckoned 30 days, EXAMPLES. OPERATION. THE number of months being 19, the greatest even number is 18, half of which is. 9, which I write down ; then seeking how 4 5 9 2 4 often 6 is contained in 41, (the sum of the 6 8 8 6 days in the odd month and the given days) 3 8 2 7 I find it will be 6 times, which I also set 2 5 5 1 down at the right hand of half the even number of months for a decimal, by which Ans. 7,4 I together I multiply the principal. In taking ir 2 Dols, tients added, with the products of half the even number of months &c. the sum of them will shew the interest required, observing to count off two more figures for decimals in the product than there are declinal figures in both the multiplier and multiplicand, counted together. For the conciseness and simplicity of the above method, it is conceived, that Instructors will recommend it to their Pupils in preference to any other cts. |
