A bank has two sites at which checks are processed. Site 1 can process 10,000 checks per day, and site 2 can process 6000 checks per day. The bank processes three types of checks: vendor, salary, and personal. The processing cost per check depends on the site (table below). Each day 5000 checks of each type must be processed. Formulate a balanced transportation problem to minimize the daily cost of processing checks. Only complete formulation needs to be submitted.
