Formula explanations will be much appreciated.

Way Cool produces two different models of air conditioners. The company produces the mechanical systems in its components department. The mechanical systems are combined with the housing assembly in its finishing department. The activities, costs, and drivers associated with these two manufacturing processes and the production support process follow. Process Activity Components Changeover Machining Setups Overhead Cost Driver $408,250 Number of batches 373,395 Machine hours 184,500 Number of setups $966,145 Quantity 710 8,030 100 Finishing Welding Inspecting Rework Welding hours Number of inspections Rework orders 6,400 865 180 $430,080 320,050 51,300 $801,430 $160,800 30,700 Support 480 Purchase orders Number of units 8,700 Purchasing Providing space Providing utilities 131,120 Number of units 8,700 $322,620 Additional production information concerning its two product lines follows.
