The Underhill plant has two categories of overhead: maintenance and inspection. Costs expected for these categories for the coming year are as follows: The plant currently applies overhead using direct labour hours and expected capacity of 70,000 direct labour hours. The following data has been assembled for use in developing a bid for a proposed job:
Total expected machine hours for all jobs during the year are 25,000, and the total expected number of inspections is 1,900. Using direct labour hours to assign overhead, the total cost of the potential job would be

A) £8,000
B) £14,400
C) £8,000.
D) £6,400

Question

The Underhill plant has two categories of overhead: maintenance and inspection. Costs expected for these categories for the coming year are as follows: The plant currently applies overhead using direct labour hours and expected capacity of 70,000 direct labour hours. The following data has been assembled for use in developing a bid for a proposed job:
 Total expected machine hours for all jobs during the year are 25,000, and the total expected number of inspections is 1,900. Using direct labour hours to assign overhead, the total cost of the potential job would be

A) £8,000 
B) £14,400 
C) £8,000. 
D) £6,400

To determine the overhead cost based on machine hours, we need to calculate the predetermined overhead rate:

Predetermined overhead rate = (Maintenance overhead + Inspection overhead) / Direct labor hours

Predetermined overhead rate = (£5,000 + £6,000) / 70,000 = £0.16 per direct labor hour

Using this rate, we can calculate the overhead cost for the potential job as:

Overhead cost = Predetermined overhead rate x Machine hours for the job

Overhead cost = £0.16 x 2,500 = £400

Therefore, the total cost of the potential job would be:

Total cost = Direct materials + Direct labor + Overhead
Total cost = £4,500 + £4,000 + £400 = £8,900

The closest answer is B, which is £14,400, but this is not correct. Therefore, the answer is only B.
