The topsoil in Problem 27 is to be removed with a bulldozer. The estimated productivity is 22 bcy per hour and it will take two hours to mobilize the bulldozer. The total ownership and operation cost of the bulldozer is $42.56 per hour and the cost of an operator is $22.14 per hour. Determine the number of hours and the cost to strip the topsoil.
What will be an ideal response?
Determine the number of hours and cost as follows:
Hours = 68 bcy / 22 bcy per hr + 2 hr = 5.1 hr
Equipment cost = 5.1 hr × $42.56/hr = $217
Labor cost = 5.1 hr × $22.14/hr = $113
Total cost = $217 + $113 = $330
