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 $$23\mathrm{.}15$ per hundred square feet. However, there is some question about whether the company is actually making any money on jobs for some customers$$particularly those located on remote ranches that require considerable travel time. The owner$$s 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 $(00$s$)8,000$ hundred square feet

Travel to jobs Miles driven $161,000$ miles

Job support Number of jobs $1,700$ jobs

Other $($organization$-$sustaining costs and idle capacity costs$)$ None Not applicable

The total cost of operating the company for the year is $$345,000$ which includes the following costs:

Wages $ $146,000$

Cleaning supplies $25,000$

Cleaning equipment depreciation $7,000$

Vehicle expenses $34,000$

Office expenses $57,000$

President$$s compensation $76,000$

Total cost $ $345,000$

Resource consumption is distributed across the activities as follows:
