The revenue equation? (in hundreds of millions of? dollars) for barley production in a certain country is approximated by:
R(x)=0.0629x^2 + 1.3288x + 2.1059 where x is in hundreds of millions of bushels. Find the? marginal-revenue equation and use it to find the marginal revenue for the production of the given number of bushels.
?(a) The? marginal-revenue equation is R′(x) =
?(Round to four decimal places as? needed.)
?(b) Find the marginal revenue for the production of 100,000,000 bushels.
The marginal revenue is:
?(Integer or decimal rounded to two decimal places as? needed.)
?(c) Find the marginal revenue for the production of 450,000,000 bushels.
The marginal revenue is:
?(Integer or decimal rounded to two decimal places as? needed.)
