1. Express the objective of maximizing the total contribution margin subject to the assembly-hour constraint. Objective function: MaxZ=$400A+$800B Subject to: A+ 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 mix. x 3. What if market conditions are such that Patz can sell at most 100 units of Part A and 80 units of Part B? Express the objective function with its associated constraints for this case. Objective function: MaxZ=$400A+$800B Assembly-hour constraint Demand constraint for Part A A Demand constraint for Part B B Identify the optimal mix and its associated total contribution margin. Component A \& units Component B \$ units Total contribution
