How do I find 2a?

Problem 2-20 (Static) Plantwide versus Multiple Predetermined Overhead Rates: Service Industry [LO2. 1, LO2-2, LO2-3, LO2-4] McCullough Hospital uses a job-order costing system to assign costs to its patients, Its direct materials include a variety of items such as pharmaceutical drugs, heart valves, artificial hips, and pacemakers. Its direct labor costs (e. 9 , surgeons, anesthesiologists. radiologists, and nurses) associated with specific surgical procedures and tests are traced to individual patients. All other costs, such as depreciation of medical equipment, insurance, utlities, incidental medical supplies, and the labor costs associated with around-theclock monitoring of patients are treated as overhead costs. Historically. McCullough has used one predetermined overhead rate based on the number of patient-days (each night that a patient spends in the hospital counts as one patient-day) to allocate overhead costs to patients. Recently a member of the hospital's accounting staff has suggested using two predetermined overhead rates (allocated based on the number of patient-days) to improve. the accuracy of the costs allocated to patients. The first overhead rate would include all overhead costs within the Intensive Care Unit (ICU) and the second overhead rate would include all Other overhead costs. Information pertaining to the hospital's estimated number of patient-days, its estimated overhead costs, and two of its patients-Patient A and Patient B- is provided below: Required: 1. Assuming McCullough calculates two overhead rates as recommended by the staff accountant, calculate: a. The ICU and Other overhead rates. b. The total cost, including direct materials, ditect labor and applied overhead, assigned to Patient A and Patient B. 2. Assuming McCullough continues to use only one predetermined overhead rate, calculate: a. The predetermined overhead rate. b. The total cost, including direct matenals, direct labor and applied overhead, assigned to Patient A and Patient B. (Round "Predetermined overhead rate" to 2 decimal ploces. Round other intermediote calculations and finol answers to the neorest dollar omount.)
