Patten Company uses activity-based costing (ABC). Patten manufactures toy cars using two activities: plastic injection molding and decal application. Patten's 20X1 total budgeted overhead costs for these two activities are $492,000 (90% for injection molding and 10% for decal application). Molding overhead costs are driven by the number of pounds of plastic that are molded together. Decal application overhead costs are driven by the number of decals applied to toys. The budgeted activity data for 20X1 are as follows:
Line Item DescriptionNumerical DataPounds of plastic molded1,940,000Number of decals applied197,000
Required:
1. Calculate the activity rate for the plastic injection molding activity. Round your answer to the nearest cent.

Comparing ABC and Plantwide Overhead Cost Assignments
Castle Dale Company uses activity-based costing (ABC). The controller identified two activities and their budgeted costs:
Line Item DescriptionAmountSetting up equipment$660,000Other overheard$2,376,000
Setting up equipment is based on setup hours, and other overhead is based on oven hours.
Castle Dale produces two products, Fudge and Cookies. Information on each product is as follows:

Sample Solution
1. Calculating Activity Rates:
a) Plastic injection molding:
Total budgeted overhead cost: $492,000 * 90% = $442,800
Budgeted pounds of plastic molded: 1,940,000 pounds
Activity rate: $442,800 / 1,940,000 pounds = $0.23 per pound molded (rounded to nearest cent)
Full Answer Section
Decal application:
Total budgeted overhead cost: $492,000 * 10% = $49,200
Budgeted number of decals applied: 197,000
Activity rate: $49,200 / 197,000 = $0.25 per decal applied (rounded to nearest cent)
Castle Dale Company: Comparison of ABC and Plantwide Overhead
Setting up equipment: 16,000 batches * $44/batch = $704,000
Other overhead: 2,200 hours * $135/hour = $297,000
Total overhead: $704,000 + $297,000 = $1,001,000
3. Unit Overhead for Fudge:
Total overhead: $1,001,000
Batches produced: 16,000
Unit overhead: $1,001,000 / 16,000 = $62.56 per unit (rounded to nearest cent)
4. Plantwide Overhead Rate:
Total budgeted overhead: $660,000 + $2,376,000 = $3,036,000
Budgeted oven hours: 17,600 hours
Plantwide overhead rate: $3,036,000 / 17,600 hours = $172.44 per oven hour (rounded to nearest cent)
5. Total Overhead for Fudge using Plantwide Rate:
Oven hours: 2,200 hours
Plantwide overhead rate: $172.44/hour
Total overhead: 2,200 hours * $172.44/hour = $377,568
6. Comparison of Overhead Assignments:
a) Reason for difference:
The difference in total overhead assigned to Fudge between the ABC system and the plantwide method is primarily due to the different treatment of setup costs. The ABC system assigns a significant portion of overhead to Fudge based on its setup hours, while the plantwide method simply spreads the total overhead cost evenly across all units based on oven hours. This results in Fudge being assigned more overhead under the ABC system because it requires more setup time per unit.
b) Difference in total overhead:
ABC system: $1,001,000
Plantwide system: $377,568
Difference:$623,432
In conclusion, the ABC system provides a more accurate allocation of overhead costs to products based on their actual consumption of resources, particularly relevant for products with significant differences in setup times.
