Prices and Values. 



1. If our average corn crop for the last five years ending with 1912 has

 United States? 



2. If 2 per cent, of the corn crop of the U. S. was exported each year, 

 what was the number of bushels exported annually? 



3. What must be the production of corn per acre at the present price 

 of corn to equal six per cent, interest on land that is valued at $200 

 per acre? 



4. If the total cost for rent and labor is $14 per acre, what must be 

 the yield to cover the total expense?

 acre, his taxes are $1 per acre, the cost of labor in producing the 

 crop is $9 per acre, how much interest does he receive on his investment at 

 the present market price of corn?
