Answer:
WoolCorp
1. Single Plantwide Factory Overhead Rate: $652
2. Comparison of WoolCorp’s current method with activity-based costing:
Raw Wool Wool Yarn
Allocated factory
overhead cost $45,640 $19,560
Activity-Based Costing $17,840 $47,640
3. Calculation of and entering the activity rate for each of the three activities:
Activity Activity Rate
Sorting $6.40 ($25,600/4,000)
Cleaning $6.00 ($38,400/6,400)
Combing $12.00 $1,200/100)
4. Allocation of the costs of sorting, cleaning, and combing to product:
Raw Wool Wool Yarn
Sorting cost $5,120 $20,400
Cleaning cost 11,520 26,880
Combing cost 840 360
Total cost $17,840 $47,640
5. Recommended method of costing:
Activity-based costing, because it recognizes differences in how each product uses factory overhead activities, yielding more accurate product costs.
Explanation:
Key Decisions: product offerings, pricing, and vendors
Problem: method of assigning overhead to products
Products:
(1) raw, clean wool to be used as stuffing or insulation and
(2) wool yarn for use in the textile industry
Requirement: evaluate its costing methods for its raw wool and wool yarn.
Traditional Costing Method : Predetermined overhead rate computed as follows:
Single Plantwide Factory Overhead Rate= (Total Budgeted Factory Overhead) ÷ (Total Budgeted Plantwide Allocation Base) combing machine hours
Data for the production of 550 pounds of either raw wool or wool yarn:
Factory Overhead Type Budgeted Factory Overhead
Sorting $25,600
Cleaning $38,400
Combing $1,200
Total overhead $65,200
Raw Wool Wool Yarn
Hours of combing
machine use required 70 30
Compiled Information:
