Erte, Inc., manufactures two models of high-pressure steam valves, the XR7 model and the ZD5 model. Data regarding the two products follow Product Direct Labor-Hours Annual Production Total Direct Labor- Hours 4,000 DLHs XR7 ZD5 0.2 DLHs per unit 20,000 units 0.4 DLHs per unit 40,000 units 16,000 DLHS 20,000 DLHs Additional information about the company follows: a. Product XR7 requires $35 in direct materials per unit, and product ZD5 requires $%25. b. The direct labor rate is $20 per hour. c. The company has always used direct labor-hours as the base for applying manufacturing overhead cost to products. Manufacturing overhead totals $1.480,000 per year. d. Product XR7 is more complex to manufacture than product ZD5 and requires the use of special milling machine. e. Because of special work required in (d) above, the company is considering the use of activity-based costing to apply overhead cost to products. Three activity cost pools have been identified and the first-stage allocations have been completed. Data concerning these activity cost pools appear below: Activity Cost PoolActivity MeasureEstimated Total Cost 80,000 300,000 1,000,000 $1,480,000 Estimated Total Activi XR7 ZD5 Total chine setups Number Special millin 100 0 4,00016,000 150 1,000 250 1,000 20,000 of setups Machine-hours Direct labor-hours General facto REQUIRED 1.
