Jack owns a snow plowing business in Maine. During the winter $($from late September to early May$),$ Maine receives a heavy amount of snowfall. Jack owns $20$ trucks that are used to plow the snow. Over the past ten years, he has had difficulty satisfying customer demand during snowfalls over $10$ inches. Jack believes that these difficulties arise due to the lack of power $($aka$,$ torque$)$ in a few of the trucks. A few trucks have such a low level of torque that they are unable to successfully push through the heavier snow. Prior to the winter of $2008,$ Jack decides to purchase new trucks that will address this issue.
