Air Force Training Program
An Air Force introductory course in electronics uses a personalized
system of instruction whereby each student views a videotaped
lecture and then is given a programmed instruction text. The
students work independently with the text until they have completed
the training and passed a test. Of concern is the varying pace at
which the students complete this portion of their training program.
Some students are able to cover the programmed instruction text
relatively quickly, whereas other students work much longer with
the text and require additional time to complete the course. The
fast students wait until the slow students complete the
introductory course before the entire group proceeds together with
other aspects of their training.
A proposed alternative system involves use of computer-assisted
instruction. In this method, all students view the same videotaped
lecture and then each is assigned to a computer terminal for
further instruction. The computer guides the student, working
independently, through the self-training portion of the
course.
To compare the proposed and current methods of instruction, an
entering class of 122 students was assigned randomly to one of the
two methods. One group of 61 students used the current
programmed-text method and the other group of 61 students used the
proposed computer-assisted method. The time in hours was recorded
for each student in the study. The following data are
provided.

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 $22.10 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 (00s) | 7,000 | hundred square feet |
| Travel to jobs | Miles driven | 180,500 | miles |
| 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 $352,000 which includes the following costs:
| Wages | $ | 140,000 |
| Cleaning supplies | 34,000 | |
| Cleaning equipment depreciation | 16,000 | |
| Vehicle expenses | 35,000 | |
| Office expenses | 56,000 | |
| President’s compensation | 71,000 | |
| Total cost | $ | 352,000 |
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 | 75 | % | 14 | % | 0 | % | 11 | % | 100 | % |
| Cleaning supplies | 100 | % | 0 | % | 0 | % | 0 | % | 100 | % |
| Cleaning equipment depreciation | 73 | % | 0 | % | 0 | % | 27 | % | 100 | % |
| Vehicle expenses | 0 | % | 78 | % | 0 | % | 22 | % | 100 | % |
| Office expenses | 0 | % | 0 | % | 55 | % | 45 | % | 100 | % |
| President’s compensation | 0 | % | 0 | % | 32 | % | 68 | % | 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. (Round your answers to 2 decimal places.)
|
3. The company recently completed a 400 square foot carpet-cleaning job at the Flying N Ranch—a 50-mile round-trip journey from the company’s offices in Bozeman. Compute the cost of this job using the activity-based costing system. (Round your intermediate calculations and final answer to 2 decimal places.)
|
4. The revenue from the Flying N Ranch was $88.40 (4 hundred square feet @ $22.10 per hundred square feet). Calculate the customer margin earned on this job. (Round your intermediate calculations and final answers to 2 decimal places.)

Question 1
On December 15, 2015, a public company receives an order from a customer for services to be performed on December 28, 2015. Due to a backlog of orders, the company does not perform the services until January 3, 2016. The customer pays for the services on January 6, 2016. When should revenue be recorded for the company? Why (support your argument with a principle from the textbook)?

Companies in the U.S. car rental market vary greatly in terms of the size of the fleet, the number of locations, and annual revenue. In 2011, Hertz had 320,000 cars in service and annual revenue of approximately $4.2 billion. Suppose the following data show the number of cars in service (1,000s) and the annual revenue ($ millions) for six smaller car rental companies.
| Company | Cars (1,000s) |
Revenue ($ millions) |
|---|---|---|
| Company A | 11.5 | 120 |
| Company B | 10.0 | 133 |
| Company C | 9.0 | 100 |
| Company D | 5.5 | 39 |
| Company E | 4.2 | 38 |
| Company F | 3.3 | 32 |
(a)Develop a scatter diagram with the number of cars in service as the independent variable.
(b)What does the scatter diagram developed in part (a) indicate about the relationship between the two variables? (Pick one of the options below)
There appears to be a negative linear relationship between cars in service (1,000s) and annual revenue ($ millions).
There appears to be no noticeable relationship between cars in service (1,000s) and annual revenue ($ millions).
There appears to be a positive linear relationship between cars in service (1,000s) and annual revenue ($ millions).
(c) Use the least squares method to develop the estimated regression equation that can be used to predict annual revenue (in $ millions) given the number of cars in service (in 1,000s). (Round your numerical values to three decimal places.)
ŷ = ____
(d)For every additional car placed in service, estimate how much annual revenue will change (in dollars). (Round your answer to the nearest integer.)
Annual revenue will increase by $ ___, for every additional car placed in service.
(e)A particular rental company has 6,000 cars in service. Use the estimated regression equation developed in part (c) to predict annual revenue (in $ millions) for this company. (Round your answer to the nearest integer.)
