Tinkle-Tinkle Glass Company makes glass globe paper weights for desks. The company uses a job-order cost system and predetermined overhead rates to apply manufacturing overhead cost to jobs. The predetermined overhead rate in the Fabrication Department is based on machine hours, and the rate in the Finishing Department is based on direct labor hours. At the beginning of the year, the companys management made the following estimates for the year:
Department
Fabrication Finishing
Machine hours 83,000 28,000
Direct labor hours 30,000 43,000
Direct material cost $412,000 $213,000
Direct labor cost $299,000 $692,000
Fixed manufacturing overhead cost $799,000 $279,000
Variable manufacturing overhead per machine hour $2.05 --
Variable manufacturing overhead per direct labor hour -- $2.00
Job 25 (the Christmas holiday special) was started on August 1 and completed on August 31. The companys cost records show the following information concerning the job:
Department
Fabrication Finishing
Machine hours 315 80
Direct labor hours 105 125
Direct materials cost $1,305 $1,030
Direct labor cost $880 1,085
Compute the predetermined overhead rate used during the year in the Fabrication Department. (Round to two decimal places.) Do the same for the Finishing Department. (Round to two decimal places.) Be careful to use the proper cost driver.
Compute the total overhead cost applied to Job 25 (in dollars and cents).
What would be the total cost recorded for Job 25? If Job 25 contained 50 units, what would be the unit product cost? If it contained 800 units, what would be the unit product cost? (Round to two decimal places.)
At the end of the year, the records of Tinkle-Tinkle Glass revealed the following actual cost and
operating data for all jobs during the year:
Department
Fabrication Finishing
Machines hours 87,000 31,000
Direct labor hours 32,000 30,000
Direct materials cost $424,000 $160,000
Manufacturing overhead cost $712,000 $287,000
What was the amount of actual overhead in each department at the end of the year? Was it underapplied or overapplied? (You should have a total of four answers for this question.)
