<![CDATA[This article discusses the application of the least squares and weighted least squares method to determine the amount of fuel consumption at a given distance in the use of vehicles in and out of town at the same time using mathematical models. This articleis a review of Izzo’s article [Mathematics Magazine 73(3):226-231]. Computational examples using real data show that the solution given by the weighted least squares method to a mathematical model of gasoline consumption more in line with the real situation.]]>
