got a fan and medal 4 the right answer

OpenStudy (rayep12):

x=mpg g(x)= total gas used g(x)=70/x + 70/(1.2x) Simplifying and limiting answer to whole numbers gives: 385/3x

OpenStudy (needhelpfsat1234):

so fine answer is

OpenStudy (rayep12):

385/3x as the simplified answer, and x = miles per gallon.
