A company manufactures 2 models of MP3 players. 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 2 R(x, y) = 110x + 160y-3x² - 2y – xy 110x+160y3x1 2y² - Find the marginal revenue equations R₂(x, y) = Ry(x, y) = We can acheive maximum revenue when both partial derivatives are equal to zero. Set R = 0 and Ry = 0 and solve as a system of equations to the find the production levels that will maximize revenue. I Revenue will be maximized when: X = y =
