A company has introduced a process improvement that reduces processing time for each unit, so that output is increased by $25\%$ with less material, but one additional worker required. Under the old process, $5$ workers could produce $90$ units per hour. Labor costs are $$\frac{14}{?}$ hour, and material input was previously $$\frac{20}{?}$ unit. For the new process, material is now $$\frac{14}{?}$ unit. Overhead is charged at $1\mathrm{.}9$ times direct labor cost. Finished units sell for $$32$ each.
