One hospital is evaluating its Emergency Department capacity so it knows how to expand as the county population grows. The hospital has the following information:

Resource    Number

Nurses    10

Physicians 5

X-ray Technicians 6

Examination rooms 10

Trauma bays 5

On average, nurses need to spend 30 minutes with each patient that comes in. Additionally, each physician can serve the average of 3 patients each hour. Each technician can X-ray up to 4 patients per hour. Unfortunately, 30% of all patients that come into the ED are trauma victims that need to be placed in a trauma bay. The other 70% of the patients go into normal examination rooms. Each trauma patient spends an average of 25 minutes in a trauma bay before leaving the ED (usually then being admitted to the main part of the hospital), whereas non-trauma patients spend an average of 30 minutes in an examination room before leaving the ED. If the hospital wants to expand capacity, each resource must be added in whole unit increments. (Display all of your answers in one decimal place).
