"The Blade Division of Axe Company produces hardened steel blades. One-third of Blade's output is sold to the Forestry Products Division of Axe; the remainder is sold to outside customers. Blades' estimated operating profit for the year is:Forestry OutsideDivision CustomersSales $15,000 $40,000Variable costs (10,000 ) (20,000 )Fixed costs (3,000 ) (6,000 )Operating profits. $2,000 $ 14,000Unit sales 10,000 20,000The Forestry Division has an opportunity to purchase 10,000 blades of the same quality from an outside supplier on a continuing basis. If the Blade Division is now operating at full capacity and can sell all its units to outside customers at the present selling price, what is the differential cost to Axe of requiring that the blades be made internally for the Forestry Division? (Points : 1)$2,500$5,000$7,500$10,000The statistic used to determine if the total cost function is significantly different from the fixed cost function is the (Points : 1)t-value of the b-coefficient.coefficient of determination.standard error of the estimate.coefficient of correlation.standard error of the a-coefficient"
