PLEASE HELP!!

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.g., surgeons, anesthesiologists, as depreciation of medical equipment, insurance, utilities, incidental medical supplies, and the labor costs associated with around-the clock monitoring of patients are treated as overhead costs. spends in the hospital counts as one patient-day) to allocate overhead costs to patients. Recently a member of the hits of patient-days, its estimated overhead costs, and two of its patients-Patient A and Patient B-is provided below: Required: 1. Assuming McCullough uses only one predetermined overhead rate, calculate: a. The predetermined overhead rate. b. The total cost, including direct materials, direct labor and applied overhead, assigned to Patient A and Patient B. 2. 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, direct labor and applied overhead, assigned to Patient A and Patient B. (Round "Predetermined overhead rate" to 2 decimal places. Round your intermediate calculations and final answers to the nearest dollar amount.)
