Answer: B — $2.12

The average cost of CNG (compressed natural gas) per gasoline gallon equivalent as of July 2015 was reported to be approximately $2.12. This figure is significant in the context of fuel pricing trends and the economic considerations for businesses in the trucking industry. CNG has been promoted as a cleaner alternative to gasoline and diesel, and understanding its cost relative to conventional fuels helps companies make informed decisions about fuel purchases and vehicle fleets. The price point of $2.12 illustrates CNG's competitive pricing during that period, indicating it may offer savings compared to traditional fuels, thus encouraging adoption among trucking companies looking to reduce operating costs while also potentially lowering their environmental impact. This figure also reflects broader trends in energy markets, including shifts away from petroleum products and increases in natural gas extraction. Knowledge of historical fuel prices like this can assist in strategic planning for fuel management and operational budgeting in the trucking sector.
