Cost Classification: Classify each of the costs of activities below as either unit-level, batch-level, product-level, customer-level, or organization-sustaining activities. For clarity, customers are retail stores, products are specific sizes/colors of leashes/collars or stain removers, a batch is a specific order from a customer or a production run made for inventory, and units are individual leashes, collars, or quarts of stain removers. Put an X in the appropriate category. (Note: One category per line item.)
