Gallatin Carpet Cleaning has always charged a flat fee per hundred square feet of carpet cleaned. The current fee is $$13\mathrm{.}65$ per hundred square feet. However, there is some question about whether the company is making a profit on jobs requiring considerable travel time. The owner$$s daughter suggested answering this question by designing an activity$-$based costing system using the information shown below:

Activity Cost Pool Activity Measure Activity for the Year

Cleaning carpets Square feet cleaned $(00$s$)11,500$ hundred square feet

Travel to jobs Miles driven $237,500$ miles

Job support Number of jobs $2,400$ jobs

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

The total cost of operating the company for the year is $$361,000$ which includes the following costs:

Wages $ $138,000$

Cleaning supplies $24,000$

Cleaning equipment depreciation $18,000$

Vehicle expenses $34,000$

Office expenses $71,000$

President$$s compensation $76,000$

Total cost $ $361,000$

She distributed these operating costs across her four activities as follows:

Distribution of Resource Consumption Across Activities

Cleaning Carpets Travel to Jobs Job Support Other Total

Wages $76\%12\%0\%12\%100\%$

Cleaning supplies $100\%0\%0\%0\%100\%$

Cleaning equipment depreciation $64\%0\%0\%36\%100\%$

Vehicle expenses $0\%79\%0\%21\%100\%$

Office expenses $0\%0\%61\%39\%100\%$

President$$s compensation $0\%0\%33\%67\%100\%$

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

Required:

$1)$ Prepare the first$-$stage allocation of costs to the activity cost pools.

$2)$ Compute the activity rates for the activity cost pools.

$3)$ The company recently completed a $400-$square$-$foot carpet$-$cleaning job at the Flying N Ranch$$a $55-$mile round$-$trip from the company$$s home office. Compute the cost of this job using the activity$-$based costing system.

$4)$ The revenue from the Flying N Ranch was $$54\mathrm{.}60(400$ square feet @ $$13\mathrm{.}65$ per hundred square feet$).$ Calculate the customer margin earned on this job.
