The price of one gallon of gas is $3.85$

Let, $x$ be the price of 1 gallon of gas.

Here, ratio of the quantity of gas $=12.6:1$

Ratio of price of gas $=48.51:x$

The quantity of gas and its price are in direct proportion.

$:.$ $12.6:1=48.51:x$

or, $12.6/1=48.51/x$

By cross multiplication, we have

$12.6*x=48.51$

or, $(12.6*x)/12.6=48.51/12.6rarr$ Dividing both sides by 12.6

or, $x=3.85$
