The following selected data were taken from the accounting records of Metal Manufacturing. The company uses direct-labor hours as its cost driver for overhead costs.

Month Direct-Labor HoursManufacturing Overhead

January26,000$690,000

February28,000$729,000

March37,000$888,000

April29,000$751,500

May33,000$789,000

June31,000$786,000

March's costs consisted of machine supplies ($170,200), depreciation ($27,000), and plant maintenance ($690,800). These costs exhibit the following respective behavior: variable, fixed, and semivariable.

The manufacturing overhead figures presented in the preceding table do not include Metcalf's supervisory labor cost, which is step-fixed in nature. For volume levels of less than 15,000 hours, supervisory labor amounts to $72,000. The cost is $144,000 from 15,000-29,999 hours and $216,000 when activity reaches 30,000 hours or more.

1.What is the machine supplies cost and depreciation for January.

2.Using the high-low method, analyze Metal's plant maintenance cost and calculate the monthly fixed portion and the variable cost per direct-labor hour.

3.Assume that present cost behavior patterns continue into the latter half of the year. What is the total amount of manufacturing overhead the company can expect in November if 28,800 direct-labor hours are worked.
