the demand equation for corn in a country is given by p=f(x)= (125/x^2+1), where p is expressed in dollars per bushel and x, the quantity demanded each year, is measured in billions of bushels. it is forecasted a harvest of 6 billion bushels for the year. if the actual production of corn were 6.2 billion bushels for the year, what would be the approximate drop in the predicted price of corn per bushel?
