Hamilton, Inc. has two divisions, Parker and Blaine. Following is the income statement for the previous year:

	Parker	Blaine

Variable Costs	600,000	450,000
Contribution Margin	$600,000	$350,000
Fixed Costs	450,000	390,000
Net Operating Income	$150,000	($40,000)

Of the total fixed costs, $600,000 are common fixed costs that are allocated equally between the divisions. What would Hamilton's net operating income be if Blaine were dropped?
