A homeowner's monthly bill shows they used 17 CCF of natural gas. How many Btu's did they use?

To determine how many British Thermal Units (Btu) were used by the homeowner who consumed 17 CCF (hundred cubic feet) of natural gas, it's essential to know the conversion factor between CCF and Btu.

Natural gas is generally measured in CCF, and the average energy content of natural gas is approximately 1,000 Btu per cubic foot. Thus, to convert CCF to Btu, you would multiply the number of CCF by the number of Btu in each CCF. Since 1 CCF equals 100 cubic feet, this means that each CCF contains about 100,000 Btu (1,000 Btu/cubic foot × 100 cubic feet).

Calculating for 17 CCF:

• 17 CCF x 100,000 Btu/CCF = 1,700,000 Btu.

However, the answer options provided suggest a slight variation, likely accounting for specific energy contents based on regional standards or variations in the gas supplier's energy content. In some cases, the average energy content for natural gas can range around 1,020 Btu cubic foot, which could lead to slightly adjusted calculations.

If you apply 1,020 Btu
