Answer and Explanation:
Labor Productivity in Units per hour
Labor Hours Productivity(In units) =  Total Output / Input hours
For Deluxe Cars =  5,000 units / 21,250 hours = 0.24 units per hour (approx)
For Limited Cars =  6,250 units / 29,950 hours = 0.21  units per hour (approx)
Labor Productivity in dollars
Labor Hours Productivity(In dollars) =  Total Output in dollar / (Input hours x rates)
For Deluxe Cars =  (5,000 units x $8,500) / (21,250 hours x $13) = $42,500,000 / $276,250 = $153.84 per unit
For Limited Cars =  (6,250 units x $10,100) / (29,950 hours x $15) = $63,125,000 / $499,250 = $126.44 per unit
