Siegel Company manufactures a product avaliable in a deluxe model and a regular model. The company has manufactured the regular model for years. The deluxe model was introduced several years ago to tap a new segment of the market. Since introduction of the deluxe model, the company's profits have steadily declined and management has become increasingly concerned about the accuracy of its costing system. Sales of the deluxe model have been increasing rapidly. Manufacturing overhead is assigned to products on the basis of direct labor-hours. For the current year, the company estimated it will incur $7,240,200 in manufacturing overhead cost and produce 21,000 units of the deluxe model and 127,000 units of the regular model. The deluxe model requires 2.0 direct labor-hours per unit, and the regular model requires 1.0 direct labor-hour. Material and labor costs per unit are as follows: Required: 1-a. Using direct labor-hours as the base for assigning mathufacturing overhead cost to products, compute the predetermined overhead rate. 1.b. Determine the unit product cost of each model. 2. Management is considering using activity-based absorption costing to apply manufacturing overhead cost to products. The activitybased system would have four activity cost pools: Calculate an activity rate for each of the four activity cost pools. 3. Using the activity rates from part (2): a. Compute the total manufacturing overhead cost applied to each model. Also, calculate each model's manufacturing overhead cos per unit. b. Compute each model's unit product cost (including direct materials, direct labor, and manufacturing overhead). Complete this question by entering your answers in the tabs below. Using direct labor-hours as the base for assigning manufacturing overhead cost to products, compute the predetermined overhead rate. Note: Round your answer to 2 decimal places
