Your engineering consulting firm is in the middle of a very profitable year. Yet, you have some engineers that have some idle time. You can either give them time off or find some work for them. The variable cost for the engineers is $30/hour and the standard cost is $55/hour. A possible job has become available. Your engineering estimator tells you that it will take at most 250 hours, at least 150 hours and most likely 180 hours. How would you decide how much to charge? What is the least you would be willing to charge? Use real numbers wherever possible. Justify your steps.
