Constrained Optimizabon: One Internal Binding Constraint Wetzel Compary produces two types of machine parts: Part A and Part B, with unit contribution margins of $300 and $600, respectively. Assume intally that Wetnel can self all th s produced of ether component. Part A requires two hours of assembly, and E requires five hours of assembly. The firm has 300 assembly hours per week. Required: 1. Express the objective of maximaing the total continbution margin subject to the assembly-hour copstraint. Objective function: MaxZ=$300A+$600B Subject to: A+BS 2. Identify the optumal arnount that should be produced of each machine part. If nene of the components should be produced, enter "0" for your answer. Component A anits componery 8 unes: Identify the total contribution margin associated with thas mo. 4 3. What if makket condtions are such that Wetrel can sell at most 75 uniss of Part A and 60 unts of Part B) Express the objective function wath its associated constrants for this case: Objective function: MaxZ=$300A+$600B Aisembit hert eonstraint A+B Subject to: A+B 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. Identify the total contribution margin associated with this mix. s 3. What if market conditions are such that Wetzel can sell at most 75 - units of Part A and 60 units of Part B?
