A small furniture manufacturer produces tables and chairs. Each product must go through three stages of the manufacturing process – assembly, finishing, and inspection. Each table requires 3 hours of assembly, 2 hours of finishing, and 1 hour of inspection. The profit per table is $120 while the profit per chair is $80. Currently, each week there are 200 hours of assembly time available, 180 hours of finishing time, and 40 hours of inspection time. Linear programming is to be used to develop a production schedule. Define the variables as follows: T = number of tables produced each week C= number of chairs produced each week According to the above information, what would the objective function be? (a) Maximize T+C (b) Maximize 120T + 80C (c) Maximize 200T+200C (d) Minimize 6T+5C (e) none of the above According to the information provided in Question 17, which of the following would be a necessary constraint in the problem? (a) T+C ≤ 40 (b) T+C ≤ 200 (c) T+C ≤ 180 (d) 120T+80C ≥ 1000…
