Constrained Optimization: One Internal Binding Constraint requires three hours of assembly, and B requires six hours of assembly. The firm has 450 assembly hours per week. Required: 1. Express the objective of maximizing the total contribution margin subject to the assembly-hour constraint. Objective function: MaxZ=$450A+$840B Subject to: 2. Identify the optimal amount that should be produced of each machine part. If none of the components should be produced, enter "0" for your answer. Component A units Component B units Identify the total contribution margin associated with this $ 3. What if market conditions are such that Wetzel can sell at most 110 units of Part A and 90 units of Part B? Express the objective function with its associated constraints for this case.
