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 630 820 1,450 Equipment-hours used 220 110 330 Direct labor-hours 480 170 650 Direct labor costs $ 38,400 $ 10,200 $ 48,600 Overhead costs $ 45,720 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 $ 4,740 Equipment-hours Supplies 12,550 Labor-hours Indirect labor and supervision 18,650 Labor-hours Equipment depreciation and maintenance 6,440 Equipment-hours Miscellaneous 3,340 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.
