Question 1203515
.
<pre>
Write an equation

    65 + 0.26*m = 83   dollars,


where "m" means miles;  then solve it

    0.26m = 83 - 65 = 18,

       m            = 18/0.26 = 69.23  miles.    <U>ANSWER</U>


Or solve it in one single line

    m = {{{(83-65)/0.26}}} = {{{18/0.26}}} = 69.23 miles

and get the same answer.


Probably, they want you round 69.23 to 69 miles.

Solved.



Choose any one of these two ways. 
They both are equally simple, clear and straightforward.
But the shortest one will teach (will train) your mind to work better, faster and sharper.
