Polaris Manufacturing uses an activity-based costing system with the following activity rates: Activity Cost Pools Activity Rate Material handling $42.75 per material movement Quality inspection $63.20 per inspection Machine setup $87.50 per setup Last month, Product XC-205 required 18 material movements, 12 quality inspections, and 15 machine setups. How much overhead cost would be assigned to Product XC-205 using the activity-based costing system?

Seacrest Company uses a process-costing system. The company manufactures a product that is processed in two departments: A and B. As work is completed, it is transferred out. All inputs are added uniformly in Department A. The following summarizes the production activity and costs for November: Required: 1. Using the weighted average method, prepare the following for Department A: (a) a physical flow schedule, (b) an equivalent unit calculation, (c) calculation of unit costs (Note: Round to four decimal places.), (d) cost of EWIP and cost of goods transferred out, and (e) a cost reconciliation. 2. CONCEPTUAL CONNECTION Prepare journal entries that show the flow of manufacturing costs for Department A. Use a conversion cost control account for conversion costs. Many firms are now combining direct labor and overhead costs into one category. They are not tracking direct labor separately. Offer some reasons for this practice.

Rex Industries has identified three different activities as cost drivers: machine setups, machine hours, and inspections. The overhead and estimated usage are: Compute the overhead rate for each activity.

Rocks Industries has identified three different activities as cost drivers: machine setups, machine hours, and inspections. The overhead and estimated usage are: Compute the overhead rate for each activity.

Wrappers Tape makes two products: Simple and Removable. It estimates it will produce 369,991 units of Simple and 146,100 of Removable, and the overhead for each of its cost pools is as follows: It has also estimated the activities for each cost driver as follows: Â How much is the overhead allocated to each unit of Simple and Removable?

The management of Wheeler Company has decided to develop cost formulas for its major overhead activities. Wheeler uses a highly automated manufacturing process, and power costs are a significant manufacturing cost. Cost analysts have decided that power costs are mixed; thus, they must be broken into their fixed and variable elements so that the cost behavior of the power usage activity can be properly described. Machine hours have been selected as the activity driver for power costs. The following data for the past eight quarters have been collected: Required: 1. Prepare a scattergraph by plotting power costs against machine hours. Does the scatter-graph show a linear relationship between machine hours and power cost? 2. Using the high and low points, compute a power cost formula. 3. Use the method of least squares to compute a power cost formula. Evaluate the coefficient of determination. 4. Rerun the regression and drop the point (20,000; 26,000) as an outlier. Compare the results from this regression to those for the regression in Requirement 3. Which is better?

Roberts Company produces two weed eaters: basic and advanced. The company has four activities: machining, engineering, receiving, and inspection. Information on these activities and their drivers is given below. Overhead costs: Required: 1. Calculate the four activity rates. 2. Calculate the unit costs using activity rates. Also, calculate the overhead cost per unit. 3. What if consumption ratios instead of activity rates were used to assign costs instead of activity rates? Show the cost assignment for the inspection activity.

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 controller of the South Charleston plant of Ravinia, Inc., monitored activities associated with materials handling costs. The high and low levels of resource usage occurred in September and March for three different resources associated with materials handling. The number of moves is the driver. The total costs of the three resources and the activity output, as measured by moves for the two different levels, are presented as follows: Required: 1. Determine the cost behavior formula of each resource. Use the high-low method to assess the fixed and variable components. 2. Using your knowledge of cost behavior, predict the cost of each item for an activity output level of 9,000 moves. 3. Construct a cost formula that can be used to predict the total cost of the three resources combined. Using this formula, predict the total materials handling cost if activity output is 9,000 moves. In general, when can cost formulas be combined to form a single cost formula?

Lonsdale Inc. manufactures entry and dining room lighting fixtures. Five activities are used in manufacturing the fixtures. These activities and their associated budgeted activity costs and activity bases are as follows: Corporate records were obtained to estimate the amount of activity to be used by the two products. The estimated activity-base usage quantities and units produced follow: a. Determine the activity rate for each activity. b. Use the activity rates in (a) to determine the total and per-unit activity costs associated with each product. Round to the nearest cent.
