CORN POKK. 195 



selling for 50 cents per bushel and pork for only 5 cents per 

 lb., it would be most profitable to sell the corn ; but should 

 corn be selling for 40 cents per bushel and pork for 6 cents 

 per lb., it would be most profitable to reduce the corn to 

 pork, and sell the latter. 



To find the price of pork per lb., taking the price of corn 

 per bushel as the datum. 



HULE. Divide the price of a bushel of corn by 8.40 (the 

 number of Ibs. of pork produced by a bushel of corn), and the 

 quotient will be the answer. 



EXAMPLE. When corn is 20 cents per bushel, what should 

 be the price of pork per lb. ? 



SOLUTION. 20.00 cents, ^-8.40 Ibs., =2.38 cents. Ans. 



To find the price of corn per bushel, taking the price of 

 pork per lb. as tJie datum. 



RULE. Multiply the price of a lb. of pork by 8.40 (the 

 number of Ibs. of pork produced by a bushel of corn), and 

 the product will be the answer. 



EXAMPLE. What should be the price of corn per bushel 

 when pork is selling at 4 cents per lb. 



SOLUTION. 4.50 cents, x 8.40 Ibs. ,37.8 cents. Ans. 



NOTE. The foregoing table and rules must not be taken 

 as invariably correct. It requires but little reflection to 

 satisfy the farmer that the proportions and results exhibited 

 by them must be influenced by many conditions and causes, 

 such as the sample of corn used, the constitution and breed
