cle. If there be several hundred pounds of it, multiply the value of 1001t. thus found, by the number of hundreds, and you will have the answer accordingly. The whole may be done by a single glance of the mind. Parts of a cent in the price of 1 pound, will be the same parts of a dollar in the price of 100 pounds. 1001t. at 1 cent per th.=100 cents=1 dollar.
Therefore, 1001t. of beef, at 4 cents a Ib. will come. to 400 cts.=84. What will 500 1. of pork come to at 8 cts. a I.?
Your mind tells you 8 cts. a Ib. is $8 a 100 pounds, and 8 multiplied by 5 is 40; of course the answer is $40.

A SHORT RULE. When the value of 1001f of any article is given, te find, mentally, what it is per th.
Rule.-Call the dollars in the price of 100th, cents, and that is tbe answer. If the value of several 100tb. is given, first divide, in your mind, the dollars in the price of the hundreds, by the number of hundreds, and the quotient will be the price of one hundred, in dollars, which call cents, as before directed, and that will be the answer. When the price of the 100 lt, in either case, contains parts of a dollar, the parts of a dollar become parts of a cent in the price of the the
1001 valued at $5=100 16 valued at 500 cents; and 500 cents-;-100=5 cents. Therefore if 100th of beef cost 6 dollars, or 600 cents, it cost 6 cts. a Ibi
What will a 15 of pork be worth, when 800th are worth $48?
Your mind tells you 8001 for $48 will be 1001t for $6, or $48 divided by 8, the number of hundreds, will give $6 for the quotient, or price of 1 hundred ; of course the price of a pound, or the answer, is 6 cents.

* As a dollar is oor x of a pound, it is plain that annexing a cipher to the pounds, and dividing by 3, will give a quotient in dollars; and annexing other ciphers, and dividing by 3, will give tenths, hundredths, &c. of a dollar; or dimes, cents, &c.
CASE II.-If pounds and shillings are given, to the pounds annex half the number of shillings, and two ciphers, if the number of shillings be even ; but if the number be odd, annex half the even number, and then 5 for the odd shilling, and one cipher, and divide by 3; the quotient is the answer in cents.
EXAMPLES. 1. Reduce £64 16s. to dollars and cents.
CASE III.-If there are shillings, pence, &c. in the given sum, annex for the shillings as before, and to these add the farthings contained in the pence and farthings; observing to increase their number by 1 when they exceed 12, and by 2 when they exceed 36 ; and divide as before.

If there be mills, cut off four figures, and proceed as before.
