Problem 17-1A Combat Fire, Inc. manufactures steel cylinders and nozzles for two models of fire extinguishers: (1) a home fire extinguisher and (2) a commercial fire extinguisher. The home model is a high-volume (54,000 units), half-gallon cylinder that holds 2 1/2 pounds of multi-purpose dry chemical at 480 PSI. The commercial model is a low-volume (10,200 units) two-gallon cylinder that holds 10 pounds of multi-purpose dry chemical at 390 PSI. Both products require 1.5 hours of direct labor for completion. Therefore, total annual direct labor hours are 96,300 or [1.5 hours (54,000 + 10,200). Expected annual manufacturing overhead is S 1,588,400. Thus, the predetermined overhead rate is 16.4g or ($1,588,400 96,300) per direct labor hour. The direct materials cost per unit is S 18.50 for the home model and $26.50 for the commercial model. The direct labor cost is $19 per unit for both the home and the commercial models. The company's managers identified six activity cost pools and related cost drivers and accumulated overhead by cost pool as follows Expected Use of Drivers by Product Expected Use of Cost Drivers Activity Cost Pools Cost Drivers Estimated Overhead Home Commercial S89,900 335,000 215,000 35,000 27,000 217,000 165,000 25,500 15,500 120,000 Machine hours Number of parts Number of tests Gallons Pounds Assembling Testing 412,000 52,000 10,000 58,500 Packing and shipping 335,000 215,000 120,000 $1,588,400 Under traditional product costing, compute the total unit cost of each product.
