Bristol Fabricators, Inc., produces air purifiers in batches. To manufacture a batch of the purifiers, Bristol Fabricators, Inc., must set up the machines and assembly line tooling. 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 tooling for different models of the air purifiers. 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 June 2015: Budget Amounts 10,100 450 Actual Amounts 9,000 400 Units produced and sold Batch size (number of units per batch) Setup - hours per batch 8 6.75 8 Setup - hours per batch Variable overhead cost per setup - hour Total fixed setup overhead costs $49.00 $36,900 6.75 $51.00 $36,531 Calculate the production - volume variance for fixed overhead setup costs.
