Sorrentino Industries manufactures a variety of custom products. The company has traditionally used a plantwide manufacturing overhead rate based on machine hours to allocate manufacturing overhead to its products. The company estimates that it will incur $2,805,000 in total manufacturing overhead costs in the upcoming year and will use 15,000 machine hours.

Calculate the cost of Job 356 using the traditional plantwide manufacturing overhead rate based on machine hours. Begin by calculating the plantwide overhead rate. First identify the formula used to compute the plantwide overhead rate, then compute the rate. (Abbreviations used: MOH = manufacturing overhead; mfg. = manufacturing) = Plantwide mfg. overhead rate Up to this point, hazardous waste disposal fees have been absorbed into the plantwide manufacturing overhead rate and allocated to all products as part of the manufacturing overhead process. Recently, the company has been experiencing significantly increased waste disposal fees for hazardous waste generated by certain products, and as a result, profit margins on all products have been negatively impacted. Company management wants to implement an activity-based costing system so that managers know the cost of each product, including its hazardous waste disposal costs. Estimated Activity for this Year Description of Cost Pool Estimated Cost Cost Driver Machine maintenance costs 1,050,000 Number of machine hours 15,000 Engineering change orders 4,000 $ Hazardous waste disposal. 360,000 Number of change orders 1,395,000 Pounds of hazardous materials generated 2,805,000 4,500 $ Total overhead cost. 320 pounds of direct materials at $20 per pound 30 direct labor hours used at $50 per labor hour 80 machine hours used 5 change orders 40 pounds of hazardous waste generated 1. 2.
