Required:
- What is the expected contribution margin and operating income for the first year of operations? (4 Marks)
- By how much per unit and in total would the contribution margin change if the constraint on the level of inventories were set to $80,000? Explain your answer. (4 Marks)
- Would the optimal solution be the same if there was not a constraint on the level of inventories? Explain your answer, and calculate the change in contribution margin if any. (2 marks)
- Explain and define what is binding and slack. (2 Marks)
