Use the following problem statement to answer questions 4-6. The MNO Claim Company processes insurance claims for large national insurance companies. Most claim processing is done by a large pool of computer operators, some of whom are permanent and some of whom are temporary. A permanent operator can process 16 claims per day, whereas a temporary operator can process 12 per day, and on average the company processes at least 450 claims each day. The company has 57 computer workstations. A permanent operator generates about 0.7 claim with errors each day, whereas a temporary operator averages about 2.1 defective claims per day. The company wants to limit claims with errors to 14 per day. A permanent operator is paid $50 per day, and a temporary operator is paid $30 per day. The company wants to determine the number of permanent and temporary operators to hire to minimize costs. [Note: X1= number of permanent operators. X2 = number of temporary operators.] Which of the following objective functions is correct? MinZ501+302MinZ=501+302MaxZ=501+302
