Kearney, Inc., makes kitchen tools. Company management believes that a new model of coffee grinder would sell well at a price of $$61\mathrm{.}20.$ The company estimates unit materials costs to be $$14\mathrm{.}00$ for the model, and overhead costs would average $$25\mathrm{.}50$ per unit. The local wage rate for direct labor is $$23\mathrm{.}00$ per hour. Kearney has a goal of earning an operating profit of $20\mathrm{.}00$ 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.$)$
