Bradford Company derived the following cost relationship from a regression analysis of Its monthly manufacturing overhead cost C = $86,000 - $12M where: C = monthly manufacturing overhead cost, and M = machine hours The standard error of estimate of the regression is $9,000. The standard time required to manufacture one six-unit case of Bradford's single product is two machine hours. Bradford applies manufacturing overhead to production on the basis of machine hours, and its normal annual production is 56,000 cases. Bradford's estimated variable manufacturing overhead cost for a month in which scheduled production is 5,600 cases would be: Multiple Choice $86,000. C $134,400. $153,200. $220,400. Some amount other than these answer choices
