Question 695913
I'm traveling 490 miles.  I get 6 miles to the gallon.  Gas is $3.61.  At this rate, how much will be gas bill be?
<pre>
6 miles to the gallon is the same as 6 miles for $3.61.  So,

6 miles is to $3.61 as 490 miles is to $X

"Is to" means "over" and "as" means "equals".  So

6 miles OVER $3.61 EQUALS 490 miles OVER $X.

{{{6/3.61}}}{{{""=""}}}{{{490/X}}}

6X = 490(3.61)

6X = 1768.9
 X = {{{1768.9/6}}}
 X = $294.82 rounded to the nearestr penny.
