Owl-Eye Radiologists (OR) does various types of diagnostic imaging. Radiologists perform tests using sophisticated equipment. OR's management wants to compute the costs of performing tests for two different types of patients: those who are hospitalized (including those in emergency rooms) and those who are not hospitalized but are referred by physicians. The data for June for the two categories of patients follow. Hospital Patients Other Patients Total Units (i.e., procedures) produced 640 850 1,490 Equipment-hours used 260 140 400 Direct labor-hours 470 180 650 Direct labor costs $ 37,600 $ 10,800 $ 48,400 Overhead costs $ 52,600 The accountant first assigns overhead costs to two pools: overhead related to equipment-hours and overhead related to labor-hours. The analysis of overhead accounts by the cost accountant follows. Account Amount Related to: Utilities $ 4,830 Equipment-hours Supplies 12,620 Labor-hours Indirect labor and supervision 21,180 Labor-hours Equipment depreciation and maintenance 10,540 Equipment-hours Miscellaneous 3,430 Equipment-hours Required: a. Compute the predetermined overhead rates assuming that Owl-Eye Radiologists uses equipment-hours to allocate equipment-related overhead costs and labor-hours to allocate labor-related overhead costs. b. Compute the total costs of production and the cost per unit for each of the two types of patients undergoing tests in June.
