Gutierrez Company has four operating divisions. During the first quarter of 2014, the company reported aggregate income from operations of $199,700 and the following divisional results.

		Division
		I		II		III		IV
Sales		$248,400		$196,300		$499,900		$446,900
Cost of goods sold		202,500		190,300		302,200		246,900
Selling and administrative expenses		74,300		64,900		60,000		50,700
Income (loss) from operations		$ (28,400)		$ (58,900)		$137,700		$149,300

Analysis reveals the following percentages of variable costs in each division.

		I		II		III		IV
Cost of goods sold		77%		90%		78%		77%
Selling and administrative expenses		38%		70%		49%		59%

Discontinuance of any division would save 50% of the fixed costs and expenses for that division. Top management is very concerned about the unprofitable divisions (I and II). Consensus is that one or both of the divisions should be discontinued.
