A fume boiler is needed as divorce of the intent of a new plant. The boiler can be fired by probable gas, fuel oil, or coal. A decision must be made on which fuel to use. An separation of the requires shows that the installed require, after a while all controls, would be smallest for probable gas at $30,000; for fuel oil it would be $55,000; and for coal it would be $180,000. If probable gas is used rather than fuel oil, the annual fuel require get extension by $7500. If coal is used rather than fuel oil, the annual fuel require get be $15,000 per year near. Assuming 8% concern, a 20-year separation bound, and no salvage value, which is the most unplentiful installation?
