The revenue equation (in hundreds of millions of dollars) for barley production in a certain country is approximated by R(x) = 0.0613x2 + 1.1584x + 2.4813 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.
1) The marginal-revenue equation is R' (x) =
2) Find the marginal revenue for the production of 200,000,000 bushels
3) Find the marginal revenue for the production of 650,000,000
