SECTION V.

PER CENT.

161. Per Cent. is a contraction of per centum, Latin, signifying by the hundred, and implies that calculations are made by the hundred. Per Annum signifies by the year.

¥nterest.

ANALYSIS. 162. If I lend a neighbor 25 dollars for one year, and he allow me 6 cents for the use of each dollar, or 100 cents, how much must he pay me in the whole at the end of the year?

25

1 If he pay 6 cts.=.06 of a dollar (132) for the use of 100 .06 cts, or i dollar, he must evidently pay 25 times .06, or (86)

.06 times 25=$1.50 for the use of 25 dollars. Hence, 1.50 25-+-1.50–$26.50 is the sum due me at the end of the 25. year. The $25 is called the principal, the .06 is called

the rate percent. the $1.50 is called the interest, and the 26.50 - $26.50 is called the amount. Hence the following

DEFINITIONS. 163. Interest is a premium allowed for the use of money. The sun of money upon interest is called the principal.

The rate is the per cent. per annum agreed on, or the inte. rest of one dollar for one year, expressed decimally.

164, 165, 166, 167, SÍMPLE INTEREST.

113 The principal and interest added together are called the amount.

Interest is of two kinds, Simple and Compound.

164. The rate per cent. is expressed in hundredths of a dollar. Decimals in the rate below hundredths are parts of one per cent. The rate of interest is generally established by law. In New-England legal interest is 6 per cent. in New York 7 per cent, and in England 5 per cent. Where the rate is not mentioned in this work, 6 per cent. is understood. '

SIMPLE INTEREST.

165. Simple Interest is that which is computed on the principal only.

FIRST METHOD...

ANALYSIS. 166. 1. What is the interest of 838.12 for 2 years, 8 munths and 21 days, at 6 per cent. per annum?

$38.12 .Multiplying the principal by the rate gives the in.06 terest for one year, (161) and the interest for one year

multiplied by the number of years, is evidently the jo$2.2872 terest for the whole time. Twenty-one days are şi 2.725 of a month=0.7, and 8 mo. 21d.=8.7 mo. But months

are 12ths of a year, hence 8.7m=mo.=0.725 year, 114360 (142) and 2yr. 8mo. 210.=2.725 years, we therefore

45744 multiply 2.2872, the interest for one year, by 2,725, the 150104 number of years, and the product. $6.132, is the inter45744 est for the whole time. Hence,

$6.1326200

167. To compute the interest on any sum for any time. Rule. Multiply the principal by the rate, expressed as a decimal of a dollar, and the product will be the interest for one year. Multiply the interest thus found by the number of years, (reducing the months and days, if any, to the decimal of a year) .(145) and the product properly pointed (106, 116) will be the interest required.

Note.-In solving the following questions, the decimal of a year, when it has not terminated sooner, has been carried to four places of figures, and that will give the interest sufficiently correci for common practice. When great accuracy is required, find the number of days in the given months and days, and divide these by 365, the number of days in a year and the quotient will be the true decimal of a year.
