Current Attempt in Progress Cullumber Company estimates that annual manufacturing overhead costs will be $ 636,000. Estimated annual operating activity bases. are: direct labor cost $ 487,600, direct labor hours 40,000 and machine hours 80,000. The actual manufacturing overhead cost for the year was $ 637,060 and the actual direct labor cost for the year was $ 483,360. Actual direct labor hours totaled 39,800 and machine hours totaled 79,000. Cullumber applies overhead based on direct labor hours. Compute the predetermined overhead rate and determine the amount of manufacturing overhead applied. Determine if overhead is over-or underapplied and the amount. (Round predetermined overhead rate to 2 decimal places, es. 15.25 and all other answers to decimal places, eg. 1,525.) Predetermined overhead rate $ 15.90 per direct labor hour Manufacturing overhead applied $ Underapplied
