Nonvalue-Added Costs Lemmons Inc. has the following two activities: (1) Retesting reworked products, cost: $463,000. The retesting cost of the most efficient competitor is $225,000. (2) Welding subassemblies, cost: $1,012,500 (67,500 welding hours). A benchmarking study reveals that the most efficient level for Lemmons would use 54,000 welding hours and entail a cost of $810,000. Required: Determine the nonvalue-added cost of each activity.
