Please help me to solve question #5. The last Chegg "expert" person who answered this question got pretty much all parts of this question WRONG, as shown below. If the answer is correct this time, I will provide a thumbs up. Thank you!

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, 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, 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 2,900 $ 5,057,600 $ 266 Estimated number of patient-days Estimated fixed overhead cost Estimated variable overhead cost per patient-day Other 5,800 $ 5,608,600 $ 125 Total 8,700 $10,666,200 Direct materials Direct labor Total number of patient-days (including ICU) Number of patient days spent in ICU Patient A $ 5,400 $ 27.250 18 0 Patient B 5 7.100 $ 37,800 23 11 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 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 rote" to 2 decimal places. Round your intermediate calculations and final answers to the nearest dollar amount.) Answer is complete but not entirely correct. 1a Predetermined overhead rate 1b 2a $ 1,398.00 per patient day IS 43,080 % $ 62,570 X $ 1,83600 per patient $ 873.78 per patient- day $ 41,733 X $ 74,020 % Total cost for patient A Total cost for patient B Predetermined ICU overhead rate Predetermined Other overhead rate Total cost for patient A Total cost for patient B day X X 2b
