Determine the cost of owning and operating a truck of $20$ m$3$ having $6$ rubber

tires using the following information: the truck was bought by $40$ x $106$ I.D$,$ useful

age $=5$ years, cost of maintenance and repair is $50\%$ of annual depreciation. Annual

operation hours $=2000$ hr$.,$ annual cost of investment is $10\%$ of the average value of

the equipment. Engine $250$ hp$-$diesel, operating factor $=60\%,$ crankcase capacity $=$

$53$ liter. Time between oil change $=80$ hr$.,$ price of fuel $=500$ I.D$/$L$,$ Oil price $=3500$

I.D$/$L$,$ the age of use tires $=5000$ hr$.,$ maintenance, and repair for all tires $=15\%$ of

its depreciation. The cost of rubber tires is $=3$ x $106$ I.D$.$ Cost $($wages$)$ of operator

$=18$ x $10^3$ I.D$/$hr$.$
