Question

My car averages 35 miles to a gallon. when the price of gasoline is $3.09per gallon, what was the cost per mile

Answer 1

3.09/35 hope that helps !

Answer 2

you want dollars per mile

so you need to divide the 35 and 3.09 in such a way that and units cancel out

(dollars/gallon)/(miles/gallon)=dollar...

$cost per mile =(3.09)/(35)=0.088$

it cost about 0.088 dollars per mile
