1. What is the total contribution towards fixed costs if only Model 101 is built? Only Model 102? 2. Briefly describe what is wrong with the following reasoning: "The marginal contribution towards the fixed cost of a Model 102 exceeds the marginal contribution towards the fixed cost of a Model 101, therefore, we should produce only Model 102's." 3. What is the total contribution towards fixed costs using their current mix of 1000 Model 101 trucks and 1500 Model 102 trucks? 4. Can you demonstrate a product mix that improves on this total contribution? 5. Suppose Merton Truck was able to invest in expanding the capacity of one of its departments. Which do you think would be more worthwhile investing in, metal stamping or Model 102 assembly? Why
