Let x represent the number (in millions) of the first model made, and let y represent the number [in millions) of the second model made. The company's revenue can be modeled by the equation Rte, 3;) : 120$ + 1801:; 7 2:32 7 43:2 7 my Find the marginal revenue equations R3013) y) =' ' Rum) =\\ \\ We can achieve maximum revenue when both partial derivatives are equal to zero. Set R3 = l} and By : 0 and solve as a system of equations to the find the production levels that will maximize revenue. Revenue will be maximized when: K II
