Scannell 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 $ 1,820, 000 in total manufacturing overhead costs in the upcoming year and will use 10,000 machine hours.
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.
Expected usage and costs for manufacturing overhead activities for the upcoming year are as follows:

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)

Requirement 2. Calculate the cost of Job 352 using activity-based costing.
Begin by calculating the allocation rate for each activity. First determine the formula to compute the allocation rate in an activity-based costing system, then compute the rate for each activity. (Abbreviations used: est. = estimated, MH=machine hours, Mach.=Machine, Eng.=Engineering)
