## Description

Zubick Corporation produces and supplies 2 types of component parts to industrial equipment manufacturers. These parts are known as X123 and R907. There are 2 departments in the factory: the machining and assembly departments. The machining department has highly automated operations, while assembly has labour-intensive operations.

The manager, Rex, decided to allocate costs to the 2 products in the following manner: he divided the total overhead costs of \$1,650,000 by the total number of labour hours utilised in the factory (ie (1000 x5) plus (2000 x 15) = 35,000 DLH). Therefore his overhead rate was \$1,650,000/35,000 = \$47.14 per DLH.

The overhead allocated to each product using Rex’s rate was as follows:
Product X123 = 5 DLH x\$47.14 = \$235.70
Product R907 = 15 DLH x \$47.14 = \$707.10
But Rex was losing sales of product R907 to his competitor who was able to sell a similar product at a lower price, and recover all costs of production.
Tables 3 and 4 show how much direct labour and machine time is consumed by each product in each production department.
