The table to the right contains price-demand and total cost data for the production of projectors, where p is the X p($) C($) wholesale price (in dollars) of a projector for an annual demand of x projectors and C is the total cost (in dollars) of 280 304 129,000 producing x projectors. Answer the following questions (A) - (D). 420 428 134,900 540 168 68,000 850 62 193,000 (A) Find a quadratic regression equation for the price-demand 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 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. y =_ (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. 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. $SPS$
