always charged a flat fee per hundred square feet of carpet cleaned. The current fee is $22.65 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 Measure Activity for the Year Activity Cost Pool Cleaning carpets Square feet cleaned (00s) Miles driven 11,500 hundred square feet 407,000 miles Travel to jobs Job support Number of jobs 2,000 jobs Other (organization-sustaining costs and idle capacity costs) None Not applicable The total cost of operating the company for the year is $353,000 which includes the following costs: Wages $ 139,000 Cleaning supplies 21,000 Cleaning equipment depreciation 16,000 Vehicle expenses 34,000 Office expenses 65,000 President's compensation 78,000 Total cost $ 353,000 Resource consumption is distributed across the activities as follows: Distribution of Resource Consumption Across Activities Cleaning Travel Job Total Carpets to Jobs 73% Support Other 0% Wages 15% 12% 100% Cleaning supplies 100% 0% 0% 0% 100% Cleaning equipment depreciation 67% 0% 0% 33% 100% Vehicle expenses 0% 76% 0% 24% 100% Office expenses 0% 0% 56% 44% 100% President's compensation 0% 0% 25% 75% 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 journey from the company's offices in Bozeman. Compute the cost of this job using the activity-based costing system. 4. The revenue from the Flying N Ranch was $90.60 (400 square feet @ $22.65 per hundred square feet). Calculate the customer margin earned on this job
