Please show work trying to learn this for my class :)

Che 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 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: ICU Other Total Estimated number of patient-days Estimated fixed overhead cost Estimated variable overhead cost per patient-day 2,400 4,800 7,200 $4,108,800 $4,968,000 $9,076,800 304$ 114 Patient A Patient B Direct materials Direct labor Total number of patient-days (including ICU) Number of patient-days spent in ICU $ 4,900 6,600 $ 26,000 36,800 18 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.)
