Tamarindo Company produces speakers (Model A and Model B). Both products pass through two producing departments. Model A's production is much more labor- intensive than Model B's. Model B is also the more popular of the two speakers. The following data have been gathered for the two products: 4-17 Plantwide versus Departmental Rates; Product Costing Accuracy; Pool Rates LO2, LO3, LO4, LO5 Product Data Model A Model B 30,000 300,000 $200,000 $2,000,000 140,000 300,000 20,000 200,000 40 60 800 1,200 10,000 90,000 Units produced per year Prime costs Direct labor hours Machine hours Production runs Inspection hours Maintenance hours EXCEL Overhead Costs Setup costs Inspection costs Machining Maintenance Total $ 360,000 280,000 320,000 360,000 $1,320,000 Required 1. Compute the overhead cost per unit for each product using a plantwide rate based on direct labor hours. 2. Compute the overhead cost per unit for each product using activity-based costing 3. Suppose that Tamarindo decides to use departmental overhead rates. There are two departments: Department 1 (machine intensive) with a rate of $4.66 per machine hour, and Department 2 (labor intensive) with a rate of $1.20 per direct labor hour. The consumption of these two drivers is given below
