What is the objective function for the above scenario?

Scenario and Decision The Baltic Avenue Community Hospital has four wards which are imaginatively named Ward 1, Ward 2, Ward 3, and Ward 4. Each ward has patients admitted for the same general purpose. Each ward generates different profit levels per patient per day and each ward has different staffing requirements. Each ward must be staffed by orderlies, certified nursing assistants (CNAs), and nurses. The table below summarizes profit and staffing requirements for the wards per patient per day. (Remember, staffing requires multiple shifts so staffing levels combine staffing from all shifts.) Profit CNA Orderly 1.5 Nursing 2.0 400 4.0 Ward 1 Ward 2 600 1.0 3.0 2.0 4.0 Ward 3 300 2.0 1.0 Ward 4 100 3.0 1.0 2.0 All figures are per patient per day The hospital has 120 hours of orderly time to schedule each day, 150 hours of CNA time, and 100 nursing hours. The hospital can allocate these hours to any ward. You must recommend patient admission levels for each ward. Note: I know that this model is incomplete in several respects but this is to keep it within a reasonable scope for the assignment. If you do this correctly you will probably get some results that may not make sense from a policy or practical perspective. Don't read too much into the results. Just solve the model and report on your findings as the problem is written
