Homework Problem

A $262-$fwhp diesel$-$powered wheel loader will be used to load shot rock. This loader was purchased for $\backslash (\backslash$$ $350,000\backslash ).$ The estimated salvage value at the end of $4$ years is $\backslash (\backslash$$ $86,000\backslash ).$ The company's cost of capital is $\backslash (7\mathrm{.}2\backslash \%\backslash ).$ A set of tires costs $\backslash (\backslash$$ $36,000\backslash ).$ The work efficiency will be equal to a $45-$min hour. The engine will work at full throttle while loading the bucket $(\backslash (33\backslash \%\backslash )$ of the time$)$ and at three$-$quarter throttle to travel and dump. The crankcase capacity is $12$ gallons, and the company has a policy to change oil every $100$ hours on the job. The annual cost of repairs equals $\backslash (65\backslash \%\backslash )$ of the straight$-$line depreciation. Fuel cost is $\backslash (\backslash$$ $3\mathrm{.}25/\backslash$mathrm$\{$gal$\}\backslash ),$ and oil is $\backslash (\backslash$$ $4\mathrm{.}55/\backslash$mathrm$\{$gal$\}\backslash ).$ The cost of other lubricants and filters is $\backslash (\backslash$$ $0\mathrm{.}45/\backslash )$ hr$.$ Tire repair is $\backslash (18\backslash \%\backslash )$ of tire depreciation. The tires should give $3,400$ hours of service. The loader will work $1,600$ hours$/$year$.$ In this usage, the estimated life for bucket teeth is $120$ hr $.$ The local price for a set of teeth is $\backslash (\backslash$$ $700\backslash ).$ What is the operating cost for the loader in this application?
