O Points: 0 of 1 Save The price p (in dollars) and the demand x for a particular clock radio are related by the equation x = 2000 - 80p. (A) Express the price p in terms of the demand x, and find the domain of this function. B) Find the revenue R(x) from the sale of x clock radios. What is the domain of R? C) Find the marginal revenue at a production level of 1500 clock radios. D) Interpret R'(1600) = - 15.00. (A) p= p(x) = wave The table to the right contains price-demand and total cost data for X P($) C(S) the production of projectors, where p is the wholesale price (in 340 593 07,000 dollars) of a projector for an annual demand of x projectors and C is 480 428 120, 100 the total cost (in dollars) of producing x projectors. Answer the 620 186 135,000 following questions (A) - (D) 720 77 166,000 (A) Find a quadratic regression equation for the price-demand data, using x as the independent variable. y = 0 (Type an expression using x as the variable. Use integers or decimals for any numbers in the expression. Round the coefficients to seven decimal places as needed. Round the constant term to three decimal places as needed.)
