Historically. McCullough has used one predetermined overhead rate based on the number of patient-days (each night that a patient spends in the hospitai 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 8 -is provided below: Required: 1. Assuming McCullough caiculates 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. 2. Assuming McCullough continues to use 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. (Round "Predetermined overhead rate" to 2 decimal places. Round other intermediate calculations and final answers to the nearest dollar amount.)
