A car wash services 200 customers 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. They charge $10 per car for their standard wash job. Which of these changes would have the greatest positive impact on their productivity?

Question
