cost of Gasoline The average price of a gallon of regular gasoline in the United States on January 18, 2010 was $2.739, and one year earlier, the average price of a gallon of regular gasoline was $1.347 Suppose that the Smith family drives a 2010 GMC Yukon 1500 4WD, which has a fuel usage of 17 miles per gallon (city and highway combined). Source: Energy Information Administration, United States Department of Energy and www.fueleconomy.gov (a) Find a linear equation that gives this family\'s annual fuel cost C as a function of the number x of miles driven in one year, using the price of a gallon of regular gasoline on January 18, 2010. Give an exact answer.

Solution

a) In the year 2010 price of gaosline = $2.739

C = $2.739* no. of miles driven in one year

x is the no. of miles

= 2.739*x

b) In the year 2009 price of gaosline = $1.847

C = $1.847* no. of miles driven in one year

= 1.847x

c) C= 2.739x

= 14000*2.739

= $ 38346
