Preliminary Problem
Givens
Miles = m = 392 miles
Gallons =  G = 14 gallons
Miles per gallon = mpg
Formula
miles = miles per gallon * number of gallons.
Solve
392 = mpg * 14                         Divide by 14
392 / 14 = mpg
28 = mpg  which is really quite good.  Our vehicle gets 44 mpg but it's a 4 cylinder. It's meant to get that kind of milage.
Part A
Let x = the number of gallons used 
Let y = the number of miles driven
y = k*x
Part B
y = k* x
k =28 mpg 
11700 = 28*x
11700 /28 = x
x = 417.86 
If this is incorrect please put some more facts in. The question does not seem complete.
 
        
             
        
        
        
The gallons of oil  in the tank is 1000
A 6500 gallon storage tank is 2/13 full
The number of oil in the tank can be calculated by multiplying the amount of gallons in the tank which is 6500 by the measurement of the tank which is 2/13
= 2/13 × 6500
= 13,000/13
= 1,000
Hence 1000 gallons of oil are in the tank
