Question 1199516: A British thermal unit (Btu) is the amount of heat needed to raise the temperature of 1 pound of liquid water by 1°F. There are about 1000 Btu per cubic foot of natural gas and about 140,000 Btu per gallon of heating oil.
a. In 2010, electricity-generating power plants paid $5.27 per 1000 cubic feet of natural gas and $56.35 per 42-gallon barrel of heating oil. Express the cost of each fuel in dollars per million Btu.
b. The tank shown can be used to store heating oil. Write a formula for the
volume of the tank.
c. You pay $3.75 per gallon of heating oil to fill a new tank in which r is 1 foot. Compare your cost for heating oil in dollars per million Btu to a power
plant’s cost in part (a). How many Btu can be produced from a full tank of heating oil?
