Scattergraph method Using the data in P4-2 and a piece of graph paper: 1. Plot the data points on the graph and draw a line by visual inspection, indicating the trend shown by the data points. 2. Determine the variable cost per unit and the total fixed cost from the information on the graph. 3. Determine the variable cost to be charged to the product for the year. 4. Determine the fixed cost to be charged to factory overhead for the year. 5. Do these answers agree with the answers to P4-2? Why or why not?
Using the data in P4-2 and Microsoft Excel: 1. Separate the variable and fixed elements. 2. Determine the cost to be charged to the product for the year. 3. Determine the cost to be charged to factory overhead for the year. 4. Determine the plotted data points using Chart Wizard. 5. Determine R2. 6. How do these solutions compare to the solutions in P4-2 and P4-3? 7. What does R2 tell you about this cost model?
Patterson Company produces wafers for integrated circuits. Data for the most recent year are provided: aCalculated using number of dies as the single unit-level driver. bCalculated by multiplying the consumption ratio of each product by the cost of each activity. Required: 1. Using the five most expensive activities, calculate the overhead cost assigned to each product. Assume that the costs of the other activities are assigned in proportion to the cost of the five activities. 2. Calculate the error relative to the fully specified ABC product cost and comment on the outcome. 3. What if activities 1, 2, 5, and 8 each had a cost of 650,000 and the remaining activities had a cost of 50,000? Calculate the cost assigned to Wafer A by a fully specified ABC system and then by an approximately relevant ABC approach. Comment on the implications for the approximately relevant approach.
The cost behavior patterns below are lettered A through H. The vertical axes of the graphs represent total dollars of expense, and the horizontal axes represent production in units, machine hours, or direct labor hours. In each case, the zero point is at the intersection of the two axes. Each graph may be used no more than once. Required: Select the graph that matches the lettered cost described here. a. Depreciation of equipmentthe amount of depreciation charged is computed based on the number of machine hours that the equipment was operated. b. Electricity billflat fixed charge, plus a variable cost after a certain number of kilowatt hours are used. c. City water billcomputed as follows: d. Depreciation of equipmentthe amount is computed by the straight-line method. e. Rent on a factory building donated by the citythe agreement calls for a fixed fee payment, unless 200,000 labor hours are worked, in which case no rent need be paid. f. Salaries of repair workersone repair worker is needed for every 1,000 machine hours or less (i.e., 0 to 1,000 hours requires one repair worker, 1,001 to 2,000 hours requires two repair workers, etc.).
Larsen, Inc., produces two types of electronic parts and has provided the following data: There are four activities: machining, setting up, testing, and purchasing. Required: 1. Calculate the activity consumption ratios for each product. 2. Calculate the consumption ratios for the plantwide rate (direct labor hours). When compared with the activity ratios, what can you say about the relative accuracy of a plantwide rate? Which product is undercosted? 3. What if the machine hours were used for the plantwide rate? Would this remove the cost distortion of a plantwide rate?
Method of Least Squares, Predicting Cost for Different Time Periods from the One Used to Develop a Cost Formula Refer to the information for Farnsworth Company on the previous page. However, assume that Tracy has used the method of least squares on the receiving data and has gotten the following results: Required: 1. Using the results from the method of least squares, prepare a cost formula for the receiving activity. 2. Using the formula from Requirement 1, what is the predicted cost of receiving for a month in which 1,450 receiving orders are processed? (Note: Round your answer to the nearest dollar.) 3. Prepare a cost formula for the receiving activity for a quarter. Based on this formula, what is the predicted cost of receiving for a quarter in which 4,650 receiving orders are anticipated? Prepare a cost formula for the receiving activity for a year. Based on this formula, what is the predicted cost of receiving for a year in which 18,000 receiving orders are anticipated?

Silven Company has identified the following overhead activities, costs, and activity drivers for the coming year: Silven produces two models of cell phones with the following expected activity demands: 1. Determine the total overhead assigned to each product using the four activity drivers. 2. Determine the total overhead assigned to each model using the two most expensive activities. The costs of the two relatively inexpensive activities are allocated to the two expensive activities in proportion to their costs. 3. Using ABC as the benchmark, calculate the percentage error and comment on the accuracy of the reduced system. Explain why this approach may be desirable.
