The management of Firebolt Industries Inc. manufactures gasoline and diesel engines through two production departments, Fabrication and Assembly. Management needs accurate product cost information in order to guide product strategy. Presently, the company uses a single plantwide factory overhead rate for allocating factory overhead to the two products. However, management is considering the multiple production department factory overhead rate method.

The following factory overhead was budgeted for Firebolt:

1. Fabrication Department factory overhead $571,200.00
2. Assembly Department factory overhead 253,000.00
3. Total$824,200.00

Direct labor hours were estimated as follows:

Fabrication Department 5,100 hours

Assembly Department 4,600

Total = 9,700hours

In addition, the direct labor hours (dlh) used to produce a unit of each product in each department were determined from engineering records, as follows:

Production Departments Gasoline Engine Diesel Engine

Fabrication Department 2.8 dlh 2.2 dlh

Assembly Department 2.2 2.8

Direct labor hours per unit 5.0 dlh 5.0 dlh

Required:

a.Determine the per-unit factory overhead allocated to the gasoline and diesel engines under the single plantwide factory overhead rate method, using direct labor hours as theactivity base.

b.Determine the per-unit factory overhead allocated to the gasoline and diesel engines under the multiple production department factory overhead rate method, using direct labor hours as the activity base for each department.

c.(1) Recommend to management a product costing approach, based on your analyses in (a) and (b). (2) Give a reason for your answer.*If required, round all per-unit answers to the nearest cent.

SINGLE PLANTWIDE METHOD:

a. Determine the per-unit factory overhead allocated to the gasoline and diesel engines under the single plantwide factory overhead rate method, using direct labor hours as theactivity base. If required, round all per-direct labor hours and per-unit answers to the nearest cent.

Gasoline engine: $ per unit

Diesel engine: $ per unit

b. Determine the per-unit factory overhead allocated to the gasoline and diesel engines under the multiple production department factory overhead rate method, using direct labor hours as the activity base for each department. If required, round all per-unit answers to the nearest cent.

Gasoline engine: $ per unit

Diesel engine: $ per unit
