Step-by-step explanation:
The student is inquiring about the average price of gasoline in the United States for the year 2015. While the specific average annual price for 2015 was not provided directly in the given information, we can discern patterns in gasoline pricing through the data available. In June 2014, the average gasoline price was $3.71 per gallon. By January 2016, it had decreased significantly to $1.96 per gallon. These fluctuations in gasoline prices are determined by various factors that economists study, such as supply and demand, production costs, distribution, and various geopolitical events. Moreover, seasonal trends indicate prices are typically higher in summer when driving increases, often peaking about 10 cents higher than in winter.
