Predetermined 0H Rate Predetermined OH rate Langston Automotive Accessories applies overhead using a combined rate for fixed and variable overhead. The rate is 250 percent of direct labor cost. During the first three months of the current year, actual costs incurred were as follows: Direct Labor Cost Actual Overhead January $108,000 $264,000 February 99,000 252,240 March 102,000 252,600 a. What amount of overhead was applied to production in each of the three months? Applied OH January $ 0 February 0 March 0 b. What was the underapplied or overapplied overhead for each of the three months and for the first quarter? Note: Do not use a negative sign with your answer. January $ 0 3 February 0 3 March 0 3 Total for Quarter 0 3 Please answer all parts ofthe question. Plantwide vs. Departmental 0H Rates Roddickton Manufacturing Co. has gathered the following information to develop predetermined OH rates for the year. The company produces a wide variety of energy-saving products that are processed through two departments, Assembly (automated) and Finishing (labor intensive). Assembly Finishing Budget total overhead $1,080,720 $319,360 Budgeted total direct labor hours 18,000 64,000 Budgeted total machine hours 136,800 6,400 Note: For the following questions, round your answers to two decimal places. a. Compute a plantwide predetermined OH rate using direct labor hours. Plantwide rate using DLHs $ 0 b. Compute a plantwide predetermined OH rate using machine hours. Plantwide rate using MHs $ 0 c. Compute departmental predetermined OH rates using machine hours for Assembly and direct labor hours for Finishing. Assembly department rate using MHS $ Finishing department rate using DLHS $ 0 d. Determine the amount of overhead that would be assigned to a product that required five machine hours in Assembly and one direct labor hour in Finishing using the answers developed in (a), (b), and (c). Total OH assigned under (a) $ 0 Total OH assigned under (b) $ 0 Total OH assigned under (c) $ 0
