Answer:
Marginal revenue equation is 0.1262x +1.3878 the production of the given number of bushels.
Step-by-step explanation:
Explanation:-
Given the revenue equation is R(x)=0.0631x^2 +1.3878x +2.1447
where 'x' is in hundreds of millions of bushels.
marginal revenue formula is calculated by dividing the change in quantity sold

Now differentiating R(x) with respective to 'x' , we get

<u>conclusion</u>:-
Marginal revenue equation is 0.1262x +1.3878 where 'x' the production of the given number of bushels.
