Casey Corporation produces a special line of basketball hoops. Casey Corporation produces the hoops in batches. To manufacture a batch of the basketball hoops, Casey Corporation must set up the machines and molds. Setup costs are batch-level costs because they are associated with batches rather than individual units of products. A separate Setup Department is responsible for setting up machines and molds for different styles of basketball hoops. Setup overhead costs consist of some costs that are variable and some costs that are fixed with respect to the number of setup-hours. The following information pertains to January 2005. Static-budget Amounts Basketball hoops produced and sold 30,000 Batch size (number of units per batch) 200 Setup-hours per batch 5 Variable overhead cost per setup hour $10 Total fixed setup overhead costs $22,500 Actual Amounts 28,000 250 4 $9 $21,000 Required: For the variances compute below, please indicate whether the variance is favorable(F) or unfavorable (U) a.
