The table to the right contains price-demand and total cost data for the production of X P($) C($) projectors, where p is the wholesale price (in dollars) of a projector for an annual demand of x 280 582 112,000 projectors and C is the total cost (in dollars) of producing x projectors. Answer the following 420 392 127,100 questions (A) -(D) 650 186 154,000 720 72 175,000 (A) Find a quadratic regression equation for the price-demand data, using x as the independent variable y= (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.) (B) Find a linear regression equation for the cost data, using x as the independent variable. (Type an expression using x as the variable. Use integers or decimals for any numbers in the expression. Round to two decimal places as needed.) Use the linear regression equation found in the previous step to estimate the fixed costs and variable costs per projector. The fixed costs are $ (Round to the nearest dollar as needed.) The variable costs are $ per projector. (Round to the nearest dollar as needed.) (C) Find the break even points
