A $5\mathrm{.}25-$cubic$-$yard $($rated heaped capacity$)$ articulated wheeled loader is loading mixed moist aggregate into dump trucks from a stockpile. Assume the loader has an average haul distance of $20$ feet $($one way$),$ operates at an average speed of $2\mathrm{.}8$ miles per hour, and works $50$ minutes per hour. The static tipping load for the loader is $33,700$ pounds. The aggregate weighs $3,000$ pounds per loose cubic yard. If the average hourly ownership and operating cost is $$118$ per hour and the operator earns $$61$ per hour, what is the estimated cost per loose cubic yard to load the trucks? Assume that
