Monark Electronics uses job order costing and applies manufacturing overhead to individual jobs by using predetermined overhead rates. In Department A, overhead is applied on the basis of machine-hours, and in Department B, on the basis of direct labor hours. At the beginning of the current year, management made the following budget estimates as a step toward determining the overhead application rates. LO17-1, L017-2, LO17-3, 017-4, L017-5 PROBLEM 17.4B Job Order Costing: A Comprehensive Problenm Annual Estimates Department A Department B $450,000 $620,000 16,200 3,000 25,200 24,800 DepartmentA Department B Job no. 652 (1,000 units of product): $19,000 $1,750 $750 $1,500 60 40 180 120 Instructions a. Determine the overhead rate that should be used for each department in applying overhead costs to job no. 652. What is the total cost of job no. 652, and what is the unit cost of the product manufactured on this production order? b. Prepare the journal entries required to record the sale (on account) of all 1,000 circuit boards to Computex Computers. The total sales price was $50,000. c. d. Assume that actual overhead costs for the year were $800,000 in Department A and S615,000 in Department B. Actual machine-hours in Department A were 16,500, and actual direct labor hours in Department B were 24,000 during the year. On the basis of this information, deter- mine the over-or underapplied overhead in each department for the year
