Estimated cost and operating data for three companies for the upcoming year follow: Direct labour-hours Machine-hours Direct materials cost Manufacturing overhead cost A 51,000 25,500 $ 255,000 $ 341,700 Company B 25,500 51,000 $ 178,500 $ 300,000 38,250 12,750 $ 191,250 $ 631,125 Predetermined overhead rates are computed using the following bases in the three companies: Company A B Overhead Rate Based on Direct labour-hours Machine-hours Direct materials cost Required: 1. Compute the predetermined overhead rate to be used in each company during the upcoming year. (Round your answers to 2 decimal places.) Predetermined Overhead Rate Company A per DLH B per MH % of DMC 2-a. Assume that company A works on three jobs during the upcoming year. Direct labour-hours recorded by job are as follows: job 418, 15,300 hours; job 419, 25,500 hours; job 420, 7,650 hours. How much overhead cost will the company apply to work in process for the year? (Do not round intermediate calculations.) Overhead cost applied 2-b. If actual overhead costs total $329,500 for the year, will overhead be under-or overapplied? By how much? (Do not round intermediate calculations.) overhead cost
