Prawitt Company incurred an activity cost of $103,500 for inspecting 30,000 units of production. Management determined that the inspecting objectives could be met without inspecting every unit. Therefore, rather than inspecting 30,000 units of production, the inspection activity was limited to a random selection of 4,000 units out of the 30,000 units of production. Determine the inspection activity cost per unit on 30,000 units of total production both before and after the improvement. If required, round per unit amounts to the nearest cent. Inspection activity before improvement \& per unit Inspection activity after improvement 5 per unit
