Sweeten Company had no underapplied or overapplied manufacturing overhead costs during the month.

Required:

For questions 1-8, assume that Sweeten Company uses a plantwide predetermined overhead rate with machine-

hours as the allocation base. For questions 9-15, assume that the company uses departmental predetermined

overhead rates with machine-hours as the allocation base in both departments.

What was the company's plantwide predetermined overhead rate?

Predetermined Overhead Rate = Estimated Fixed Overhead/Estimated Direct Labor Hours + Variable Overhead

Rate Per Hour

Estimated total overhead = Estimated total fixed manufacturing overhead (26,200) + variable overhead molding

(machine hours:2500*var overhead per machine hour molding:1.70) + variable overhead fabrication (machine

hours:1500*var overhead per machine hour fabrication:2.50) = 26200 + 4250 + 3750 = 34,200

1. Plantwide predetermined rate = estimated total overhead (34,200)\estimated total machine hours (4000) =
