The gasoline gauge on a van initially read 1/8 full. When 15 gallons of gasoline were added to the tank, the gauge then read 3/4  full. How many more gallons would be needed to fill the tank?

x can represent the total gallons of gasoline.

This means that when it was $$\frac{1}{8}$$full, it is $$\frac{1}{8}$$x.

So this means $$\frac{1}{8}x+15=\frac{3}{4}x$$

Solving we get 24 gallons in the entire tank.

It is currently three-quarters full, which is 18 gallons out of a total of 24 gallons.

This means we need $$\boxed{6}$$ more gallons to fill the tank.
