Delph Company uses a job-order costing system with a plantwide predetermined overhead rate based on machine-hours. At the beginning of the year, the company estimated that 56,000 machine-hours would be required for the period's estimated level of production. It also estimated $960,000 of fixed manufacturing overhead cost for the coming period and variable manufacturing overhead of $4.00 per machine-hour. Because Delph has two manufacturing departments-Molding and Fabrication-it is considering replacing its plantwide overhead rate with departmental rates that would also be based on machine-hours. The company gathered the following information to enable calculating departmental overhead rates: Machine-hours Fixed manufacturing overhead cost Variable manufacturing overhead cost per machine-hour Molding 24,000 $ 720,000 $ 4.00. Fabrication 32,000 Total $ 240,000 $ 1.00 56,000 $ 960,000 During the year, the company had no beginning or ending inventories and it started, completed, and sold only two jobs- Job D-70 and Job C-200. It provided the following information related to those two jobs: Job D-70 Direct materials cost Total Molding $370,000 Fabrication $ 320,000 Direct labor cost Machine-hours $220,000 15,000 $ 160,000 9,000 $690,000 $380,000 24,000 Job C-200 Direct materials cost Direct labor cost Molding $300,000 $ 140,000 Fabrication $ 300,000 $ 300,000 Total $ 600,000 $440,000 Machine-hours 9,000 23,000 32,000 Delph had no underapplied or overapplied manufacturing overhead during the year. Required: 1. Assume Delph uses plantwide predetermined overhead rates based on machine-hours. a. Compute the plantwide predetermined overhead rate. b. Compute the total manufacturing cost assigned to Job D-70 and Job C-200 c. If Delph establishes bid prices that are 150% of total manufacturing costs, what bid prices would it have established for Job D-70 and Job C-200?
