The table to the right contains price-demand and total cost data for the production of projectors, X o($) C($) where p is the wholesale price (in dollars) of a projector for an annual demand of x projectors 280 558 114,000 and C is the total cost (in dollars) of producing x projectors. Answer the following questions 420 394 126,700 (A) - (D) 640 194 162,000 710 73 184,000 (A) Find a quadratic regression equation for the price-demand data, using x as the independent variable y = 812.010 - 872x - 000207x2 (Type an expression using x as the variable. Use integers or decimals for any numbers in the expression. Round the coefficients to seven decimal place 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 y = 65065 22 + 159.24x (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 $ 65065.22 (Round to the nearest dollar as needed.) The variable costs are $ 159 24 per projector (Round to the nearest dollar as needed.) (C) Find the break even points. The break even points are (Type ordered pairs, Use a comma to separate answers as needed. Round to the nearest integer as needed.) (D) Find the price range for which the company will make a profit $ SPS$
