You have just been hired by FAB Corporation, the manufacturer of a revolutionary new garage door opening device. The president has asked that you review the companys costing system and do what you can to help us get better control of our manufacturing overhead costs. You find that the company has never used a flexible budget, and you suggest that preparing such a budget would be an excellent first step in overhead planning and control.

After much effort and analysis, you determined the following cost formulas and gathered the following actual cost data for March:

	Cost Formula	Actual Cost in March
Utilities	$16,900 plus $0.21 per machine-hour	$	23,740
Maintenance	$38,300 plus $1.90 per machine-hour	$	77,700
Supplies	$0.40 per machine-hour	$	9,400
Indirect labor	$94,500 plus $1.60 per machine-hour	$	133,800
Depreciation	$67,700	$	69,400

During March, the company worked 22,000 machine-hours and produced 16,000 units. The company had originally planned to work 24,000 machine-hours during March.
