		0.143, 0.345, 0.345
		0.200, 0.400, 0.400
		0.143, 0.428, 0.428

The Dulac Box plant produces wooden packing boxes to be used in the local seafood industry. Current operations allow the company to make 500 boxes per day, in two 8-hour shifts (250 boxes per shift). The company has introduced some moderate changes in equipment, and conducted appropriate job training, so that production levels have risen to 350 boxes per shift. Labor costs average $15 per hour for each of the 5 full-time workers on each shift. Capital costs were previously $3,000 per day and rose to $3,200 per day with the equipment modifications.

		1.907 boxes per dollar
		0.146 boxes per dollar
