2x^2+2xy+2x
The ^ means exponent
So for this you will be using an exponential equation, which is
with a=initial value, b=growth/decay, y = total balance, and x = # of years
In this case, a = 500, and since with this problem the initial value is growing, you will add 100% to 6% to get 106%, or 1.06. The equation will be formed as such: 
With this problem, just plug in 15 into x and solve for y: 
In short, after 15 years Tom will have $1198.28 in his account.

Car #1: 300/43.2 = 6.9444 gallons
(Rounded) Car #2: 300/35.9 = 8.3565 gallons
~~~~~~~~~~~~~~~~~~~~~~~~~
(Rounded) Car #1: 6.9444*3.19 = $22.16 to re-fill their tank
(Rounded) Car #2: 8.3565*3.19 = $26.66 to re-fill their tank
~~~~~~~~~~~~~~~~~~~~~~~~~
(Rounded) Difference: $26.66 - 22.15 = $4.50
To re-fill Car 2's tank is approximately $4.50 more to re-fill Car 1's tank...
