The expected activity of the paper-making plant of Conroy Paper Company was 58,400 machine hours per month. Practical capacity was 73,000 machine hours per month. The standard machine hours allowed for the actual output achieved in January were 61,000. The budgeted fixed-factory-overhead items were as follows:

Depreciation, equipment …….. $339,000

Depreciation, factory building … 66,000

Supervision ……………………. 51,000

Indirect labor ………………… 232,000

Insurance ………………………. 20,000

Property taxes …………………. 22,000

Total …………………………. $730,000
