Georges Grill analyzes profitability of three operating units: restaurant, bar, and billiards room. Revenues, variable costs, and attributable fixed costs (which can be avoided if the unit is eliminated) for each unit are as follows:

Revenue	$320,000	$150,000	$40,000
Variable costs	120,000	35,000	10,000
Attributable fixed costs	80,000	25,000	15,000
