Problem 3 (20 pts) Given: A dozer cost $170,000 to purchase. Fuel, oil, grease, and minor maintenance are estimated to cost $30.00 per operating hour. A major engine repair costing $30,000 will probably be required after 7,200 hr of use. Salvage value is 25% of the original purchase price. The machine is expected to have a useful life of 11,000 hr. The company's cost-of-capital rate is 7.5%. Determine: How much should the owner of the machine charge per hour of use, if it is expected that the machine will operate 2,000 hr per year
