Gallatin Carpet Cleaning is a small, family-owned business operating out of Bozeman, Montana. For its services, the company has always charged a flat fee per hundred square feet of carpet cleaned. The current fee is $22.30 per hundred square feet. However, there is some question about whether the company is actually making any money on jobs for some customersparticularly those located on remote ranches that require considerable travel time. The owners daughter, home for the summer from college, has suggested investigating this question using activity-based costing. After some discussion, she designed a simple system consisting of four activity cost pools. The activity cost pools and their activity measures appear below:

Activity Cost Pool	Activity Measure	Activity for the Year
Cleaning carpets	Square feet cleaned (00s)	12,000	hundred square feet
Travel to jobs	Miles driven	256,000	miles
Job support	Number of jobs	1,800	jobs
Other (organization-sustaining costs and idle capacity costs)	None	Not applicable

The total cost of operating the company for the year is $357,000 which includes the following costs:

Wages	$	146,000
Cleaning supplies		22,000
Cleaning equipment depreciation		19,000
Vehicle expenses		33,000
Office expenses		57,000
Presidents compensation		80,000
Total cost	$	357,000

Resource consumption is distributed across the activities as follows:

Distribution of Resource Consumption Across Activities
	Cleaning Carpets		Travel to Jobs		Job Support		Other		Total
Wages	74	%	16	%	0	%	10	%	100	%
Cleaning supplies	100	%	0	%	0	%	0	%	100	%
Cleaning equipment depreciation	68	%	0	%	0	%	32	%	100	%
Vehicle expenses	0	%	81	%	0	%	19	%	100	%
Office expenses	0	%	0	%	64	%	36	%	100	%
Presidents compensation	0	%	0	%	30	%	70	%	100	%

Job support consists of receiving calls from potential customers at the home office, scheduling jobs, billing, resolving issues, and so on.
