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: Other Hospital Patients 680 220 480 $38,400 Patients 840 150 190 $11,400 Total Units (i.e., procedures) produced Equipment-hours used Direct labor-hours Direct labor costs Overhead costs 1,520 370 670 $49,800 $48,810 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 Utilities Supplies Indirect labor and supervision Equipment depreciation and maintenance Miscellaneous Amount Related to: Equipment-hours $ 4,820 12,510 Labor-hours 19,650 Labor-hours 8,510 Equipment-hours 3,320 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. Overhead Rate Equipment-related Labor-related per hour per hour b. Compute the total costs of production and the cost per unit for each of the two types of patients undergoing tests in June.
