Pressure Inc. manufactures two models of high-pressure steam valves, the XR7 model and the ZD5 model. Data regarding the two products follow: Direct Labor Hours per Unit Product XRT... Annual Production 20,000 units 40,000 units Total Direct Labor Hours 4.000 16,000 20,000 ZDS........ " Additional information about the company follows: a. Product XR7 requires $35 in direct materials per unit, and product ZDS 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 a special milling machine. e. Because of the special work required in (d) above, the company is considering the use of activity-based costing to apply overhead cost to products. Three activity centers have been identified as follows: Expected Activity- Estimated Cost Driver Overhead Activity Center Cost Driver Cost Total XR7 ZDS Machine setups ....... Number of setups $180,000 250 150 100 Special muling ........ Machine-hours 300,000 1,000 1,000 General factory .......
