Question

Problem 17-01A a-e 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 x (54,000 + 10,200)]. Estimated annual manufacturing overhcad is $1,576,678. Thus, the predetermined overhcad rate is $16.37 or ($1,576,678 + 96,300) per direct labor hour. The direct materlals cost per unit Is $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.

Answer 1

Under Traditional product costing,

Total unit cost

$    62.06

$    70.06

Calculations:

	Home Model	Commercial Model
Direct material cost per unit	$            18.50	$                         26.50
Direct labor cost per unit	$            19.00	$                         19.00
Manufacturing overhead per unit*	$            24.56	$                         24.56
Total unit cost	$            62.06	$                         70.06

*Manufacturing overhead per unit = Cost per direct labor hour x Direct labor hours per unit

= $16.37 x 1.5 labor hours

= $24.56

Under ABC costing,

Activity cost pool	Estimated Overhead	Estimated Use of Cost Drivers		Activity-Based Overhead Rate
Receiving	$90,450	335,000	Pounds	$0.27	per pound
Forming	$150,850	35,000	Machine hours	$4.31	per machine hour
Assembling	$405,790	217,000	Parts	$1.87	per part
Testing	$51,000	25,500	Tests	$2.00	per test
Painting	$57,838	5,258	Gallons	$11.00	per gallon
Packing and shipping	$820,750	335,000	Pounds	$2.45	per pound
	$1,576,678
