Explanation The given line graph represents ‘U.S. regular conventional retail gasoline prices’ for automotive trades. From the line graph of ‘U.S. regular conventional retail gasoline prices’, it can be observed that the cost of regular gas per gallon in the year 2007 is 3.0. That is, the cost for filling the tank per gallon is 3$. Therefore, the cost for filling 20 gallon tank will be 20 × 3 = 60 $ . Also, from the line graph note that that the cost of regular gas per gallon in the year 2001 is 1.50. That is, the cost for filling the tank per gallon in the year 2001 is 1.50$. Therefore, the cost for filling 20 gallon tank will be 20 × 1
