$($Chapter $5)$: Calculate the probable cost per hour of

owning and operating a chain dozer that has a $212$

horsepower diesel engine. The purchase price is

$$285,000$ delivered, including shipping and taxes. It is

anticipated the dozer will be operated $1,500$ hours per

year and sold for $$65,000$ after $5$ years. Assume interest

rate of $5\%$ for borrowing money, $5\%$ for risk, and $3\%$ as

the equivalent interest for taxes, insurance, and storage.

Assume $0\mathrm{.}6$ operating factor, $0\mathrm{.}6l\frac{b}{h}r$ for grease, $6$ gal

crankcase capacity, and $100$ hours between oil changes.

Use $$2\mathrm{.}95/$gal for fuel and $$3\mathrm{.}35/$gal for oil, and $$1\mathrm{.}05/$lb

for grease. Assume maintenance and repair cost as $50\%$

of annual straight$-$line depreciation cost. $($Points $15)$
