Kearney, Inc., makes kitchen tools. Company management believes that a new model of coffee grinder would sell well at a price of $61.20. The company estimates unit materials costs to be $14.00 for the model, and overhead costs would average $25.50 per unit. The local wage rate for direct labor is $23.00 per hour. Kearney has a goal of earning an operating profit of 20.00 percent of manufacturing costs for each of its products. Required: What direct labor-hour input (hours per unit) could Kearney allow and still achieve its profit goal? (Round your answer to 2 decimal places.)
