Snowden Industries produces two electronic decoders, P and Q. Decoder P is more sophisticated and requires more programming and testing than does Decoder Q. Because of these product differences, the company wants to use activity-based costing to allocate overhead costs. It has identified four activity pools. Relevant information follows: Activity Pools Cost Pool Total Cost Driver Repair and maintenance on assembly machine $ 105,600 Number of units produced Programming cost 143,400 Number of programming hours Software inspections 11,000 Number of inspections Product testing 15,000 Number of tests Total overhead cost $ 275,000 Expected activity for each product follows: Number of Units Number of Programming Hours Number of Inspections Number of Tests Decoder P 19,800 2,000 190 1,400 Decoder Q 46,200 1,000 60 1,100 Total 66,000 3,000 250 2,500 Assume that before shifting to activity-based costing, Snowden Industries allocated all overhead costs based on direct labor hours. Direct labor data pertaining to the two decoders follow: Direct Labor Hours Decoder P 6,600 Decoder Q 15,400 Total 22,000 Required Compute the amount of overhead cost allocated to each type of decoder when using direct labor hours as the allocation base. Determine the cost per unit for overhead when using direct labor hours as the allocation base and when using ABC.

Using Direct Labour hours;

The cost per unit for Decoder P=$5.76

The cost per unit for Decoder Q=$5.76

Using Activity based costing;

The cost per unit for Decoder P=$7.48

The cost per unit for Decoder Q=$5.01

Explanation:

A)Total Overhead cost= $275,000

Total Labour Hours=22,000

P Total Overhead  =6,600/22,000*$275,000=$82,500

Overhead cost per unit=$82,500+$31,680/19,800units=$5.76

Fixed cost=$105,600

19800/66000*$105,600=$31,680

Q Total overhead  =15,400/22,000*$275,000=$192,500

Overhead cost per unit=$192,500+$73,920/46,200units=$5.76

Fixed cost=$105,600

46,200/66000*$105,600=$73,920

B)Using activity based costing;

Total Overhead cost= $275,000

Repair and Maintenence Cost = $105,600

Total Labour Hours=22,000

P Overhead  =6,600/22,000*$275,000=$82,500

Overhead cost perunit=$82,500/19,800units=$4.16

P Activities overhead=(2000+190+1400)/5750*$105,600=$65,931.13

Activity cost per unit=$65,931.13/19,800units=$3.32

Total Overhead cost =$4.16+$3.32=$7.48

Q Total overhead  =15,400/22,000*$275,000=$192,500

Overhead cost per unit=$192,500/46,200units=$4.16

Q Activities overhead=(1000+60+1,100)/5750*$105,600=$39,668.87

Activity cost per unit=$39,668.87/46,200units=$0.85

Total Overhead cost =$4.16+$0.85=$5.01
