Beach Corporation, which produces a single product, budgeted the following costs for its first year of operations. These costs are based on a budgeted volume of 30,000 towels produced and sold:

Variable manufacturing overhead	$72,000
Fixed manufacturing overhead	$60,000
Variable selling and administrative expenses	$12,000
