Question 531545
While driving your car, you realize that you only have one-eighth 
of a tank of gas remaining before you run out of gas. You pull into 
a gas station and put 15 gallons of gas in your car and your gas gauge 
reveals that your car’s tank is now three-fourths full. 
How many gallons of gas does your car’s gas tank hold?
---------
Equation:
Let "x" be the tank's capacity.
----------------------------------
[(1/8)x + 15] = (3/4)x
--------
(6/8)x - (1/8)x = 15
----
(5/8)x = 15
x = (8/5)*15
x = 24 gallons (tank capacity)
