A large rear dump truck working in a coal mining operation under good conditions has a current purchase price of $ 600,000, including $ 80,000 for the initial cost of six tyres. What is the net capital cost?

If the repair factor is 0.25 x 10^-4 and for good conditions the job factor is 0.8, determine the estimated repair cost per operating hour?

If major overhaul costs are estimated at 15% of the net capital cost and this occurs every 20,000 hours determine the major overhaul cost per operating hour?

If maintenance labour costs are $50/ person hour, a single maintenance person is required and the maintenance labour requirement is estimated at 0.8 person hours per operating hour determine the maintenance labour cost?

Determine the total maintenance cost?
