I have heard that gas prices could DOUBLE over the next 18 months and even TRIPLE within 5 years.

Do you think this is true?

What will happen with gas prices in the coming years?

I think it is not only possible but probable that the spike will continue at unprecedented levels because of a few factors: 1) political unrest/instability in oil producing regions;
2) China's economic boom is resulting in increased global demand; and 3) speculating/trade manipulation/price distortion/hype; 4) OPEC's refusal to increase production;
5) population growth; and 6) continued devaluation of the dollar. Also, consider urban sprawl. More people live in suburbs and have longer commutes than years ago.
There is no quick fix to get us less energy dependent very quickly. However, if this continues at this rate, it's going to bankrupt the country and the average people. Because of the outsourcing of jobs, many people earn less than they did a few years ago. We are in a race to the bottom. We end out in a Catch 22. Jobs are overseas so people had less income. With less income, there is more pressure to continue
providing cheap goods. Cheap goods come from the third world. There is no great mass transit in this country. The fuel price increases causes inflation to increase. So, you will continue to pay more for food, etc.. Government vehicles like fire trucks and police cars and school buses will be more expensive because of fuel putting pressure on taxes.
And, companies are going to pay people less and less and less. This country is headed towards a big flush down the toilet called Earth.

do i have the legal right to demand my 0.1 penny back as change? 100% of every gas station I have ever seen prices to the tenth of a penny.
If not, it's false advertising and i should be allowed to sue them unmercifully. Am i correct or not?

Its called rounding. Its also manipulates people's minds because it looks cheaper than it actually is. I'm fairly sure its legal.

Write code for the application that allows users to calculate the expected cost of a trip as follows:

User can enter anticipated miles
User can enter anticipated cost of gas per gallon
The application should:

Provide interface options to allow the user to calculate anticipated cost and exit the application
Calculate and display the approximate cost, including oil change

Oil companies are making record profits. If those profits were regualated and they made normal profits vs. historically high profits what would a gallon of gas cost?

It would be higher. Oil companies make only a small profit per gallon, but make more in volume as it has become a necessity.

Normal profit is an oxymoron. Bottled water is $1.10 in my vending machine. That is much higher than gasoline. Water from the tap is about $0.001 per gallon.
