Fayer Products Ltd. produces water glasses in batches. To manufacture a batch of glasses, Fayer must setup 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 glasses. 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 July.
