Siva Coporation uses the weighted average process costing method. The Mixing Department at Silva had $17,000$ units in beginning inventory. These units contained $$70,000$ in direct materials, $$80,000$ in direct labor, and $$60,000$ in overhead. During the period, the department incurred costs of $$320,000$ in direct materials, $$400,000$ in direct labor and $$200,000$ in overhead and started $80,000$ units. Ending inventory consisted of $6\mathrm{.}000$ units which were $100\%$ complete with respect to direct materials and $50\%$ complete with respect to direct labor and overhead.

What is the cost per equivalent unit for direct labor $($rounded to the nearest cent$)?$
