Mars Corporation has three departments. Condensed income statement data are as follows:

Department A Department B Department C Total Sales
$300,000 $280,000 $120,000 $700,000

Variable Expenses
160,000 175,000 105,000 440,000

Contribution Margin
140,000 105,000 15,000 260,000

Net Income
$75,000 $70,000 $(25,000) $120,000

If Department C is discontinued, fixed expenses would drop $24,000 since the departmental supervisor would leave; the remaining fixed expenses would continue. Sales in Department A would drop 5%; Department B would be unaffected.
