(Click the icon to view the data.) Read the requirements. Requirement 1. What is the constraint? Griswold's constraint is machine hours. Requirement 2. Which model should Griswold produce? (Hint: Use the allocation of fixed manufacturing overhead to determine the proportion of machine hours used by each product.) Griswold should produce the product with the highest contribution margin per unit of the constraint . Now prepare the product mix analysis by starting with the contribution margin per unit. Data table 1. What is the constraint? 2. Which model should Griswold produce? (Hint: Use the allocation of fixed manufacturing overhead to determine the proportion of machine hours used by each product.) 3. If Griswold should produce both models, compute the mix that will maximize operating income
