Car wash services 200 customers in an hour on a lovely Saturday afternoon. The car wash employs 5 washers at $6 per hour and uses $50 of water and $5 of electricity per hour. An appropriate measure of productivity is A. 80%. B. 0.425 $/car. C. 8 cars/$. D. 2.35 cars/$.

Productivity = 2.35 cars / $

Explanation:

Given:

Total number of car per hour = 200

Total number of washers = 5

Wages per hour each washer = $6

Per hour water expenses = $50

Per hour electricity expenses = $5

Computation of total expenses per hour:

Total expenses per hour = (Total number of washers x Wages per hour) + Per hour water expenses + Per hour electricity expenses

Total expenses per hour = (5 x $6) + $50 + $5

Total expenses per hour = $30 + $50 + $5

Total expenses per hour = $85

Computation of productivity:

Productivity = Total number of car per hour / Total expenses per hour

Productivity = 200 / $85

Productivity = 2.35 cars / $
