A SHORT RULE. When the value of 100lt of any article is given, to find, mentally, what it is per to.
Rule.-Call the dollars in the price of 1001t. cents, and that is the answer. If the value of several 100 it. 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
When the price of the 100t: in either case, contains parts of a dollar, the parts of a dollar become
of a cent in the price of the it. 100jt valued at $5=1008 valued at 500 cents; and
Therefore if 100 it. of beef 500 cents = 100=5 cents. cost 6 dollars, or 600 cents, it cost 6 cts. a t.
What will a It of pork be worth, when 80015 are Your mind tells you 80011 for $48 will be 10011 for
