Manufacturing Optimization Carlson Manufacturing produces Macs and PCs.  The production processes are similar in that both require labor in the electronics and the assembly departments. Each Mac needs 3 hrs of electronics and 2 hrs of assembly. Each PC requires 4 hrs of electronics and 1 hr of assembly. For current month, 2,400 hrs of electronics and 1,000 hrs of assembly hrs are available. BA3051(005) wants to make no more than 450 Macs and at least 100 PCsthis month. The profit contribution for each Mac and PC are $700 and $500 respectively. Find the best possible combination of tables and chairs to manufacture this month in order to attain the max profit.   Match the correct solution for the Letters identified in the SOLVER TABLE:
