Question: The 7th National Bank has two check-processing sites. Site 1 can process 10,000 checks per day, and site 2 can process 6000 checks per day. The bank processes three types of check: vendor, salary, and personal. The processing cost per check depends on the site and is listed below.
Processing costs per check
Vendor Salary Personal
Site 1 $0.05 $0.04 $0.02
Site 2 $0.03 $0.04 $0.05
1 Each day, 5000 checks of each type must be processed. Develop a network model to determine how to minimize the daily cost of processing checks.
2. Use SolverTable to see how the total cost changes when the number of personal checks to be processed varies from 3000 to 6000 in steps of 500. Is the change in the optimal cost linear?
