Zack Manufacturing has four categories of overhead. The four categories and expected overhead costs for each category for next year are listed below:

Maintenance

P200,000

Materials handling

32,000

Set-ups

100,000

Inspection

120,000

Currently, overhead is applied using a predetermined overhead rate, based on budgeted direct labor hours. Fifty thousand direct labor hours are budgeted for next year.

The company has been asked to submit a bid for a proposed job. The plant manager feels that getting this job would result in new business in future years. Bids are based on full manufacturing cost plus 20 percent.

Estimates for the proposed jobs are as follows:

Direct Materials

P 6,000

Direct Labor (1,000 hours)

P 10,000

Number of Material moves

12

Number of Inspections

10

Number of Set-ups

2

Number of Machine hours

500

In the past, full manufacturing cost has been calculated by allocating overhead using a volume-based cost driver, direct labor hours. The plant manager has heard of a new way of applying overhead that uses cost pools and cost drivers.

Expected activity for the four activity-based cost drivers that would be used are:

Machine Hours

20,000

Material moves

1,600

Set-ups

2,500

Quality inspections

41,000

Required:

1.(a) Determine the amount of overhead that would be allocated to the proposed job if direct labor hours is used as the volume-based cost driver.
