6) Activex Corporation produces a special line of hockey sticks in batches. To manufacture a batch of sticks Activex Corp. must setup the machines. 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 for different type of sticks. Setup overhead costs consist of some costs that are variable and some costs that are fixed with respect to the number of setup hours.
