Taking a trip needing to know asap,(bad with math)

x = $55.50-First of all, you never fill up from zero gallons. 12 gallons is a mighty small tank, but that turns out to be irrelevant.To use round numbers,......
I'm going to a wedding 333 miles away,I get 30 mpg(I'll be going straight just about the while trip)
My Saturn takes 30$ to fill up, the tank gets around 12 gallons. How much gas money would it take to get there and get back?

-
distance = rate * (number of gallon)

the rate is 30 and the TOTAL distance is 333 + 333 = 666 miles
666 = 30 * g

12 gallons / 30 dollars = 0.4 gallons / dollar
number of gallon = 0.4 * x, where x is the amount of money you spend

so,
666 = 30 * (0.4) x
x = $55.50

First of all, you never fill up from zero gallons. 12 gallons is a mighty small tank, but that turns out to be irrelevant.

To use round numbers, 330 miles .÷ 30 mi/gallon = 11 gallons just to get there, You will also require about the same 11 gallons to get back. That's 22 gallons you'll use for the trip alone.

But let's assume that you fill up whenever you tank reaches 1/4 full. That will take 9 gallons with each fillup. You will need 3 fillups. 3 x 9 = 27 gallons to have more than the required 22 suing that scenario.

You may be paying at as much as $4.50 per gallon (worse case scenario).

So you will need 27 x $4.50 = $121.50. That will leave you with about 5 extra gallons when you return (You do want to get back, don't you?) If you can but gas oline for $3.50 then 27 x $3.50 = $94.50.

How much it usually costs you to "fill up" is irrelevant becasue it depends on how many gallons your tank holds and how much you have left when you fill up.

So for this trip plan for between $100-120 to fill up 3 times. *For the trip itself*, you will spend as much as 22 x $4.50 = $99. But that is not how much money you'll need to budget, since you may need to make some local trips.

Better yet ... why not just use a credit card and use as much as you need and pay for it when you get the bill?

So 333/ 30 gives us 11.1 gallons of gas to get there. And if you can fill up your tank at 12 gallons of gas for $30 it will only cost you 27.75. You average $2.50 ? well thats very cheap for gas though, i would expect it to cost more then the numbers you gave me.

But according to your numbers it will cost you about $27.75 to get there, times that by two gives you $55.50.

-
Allow yourself $75 for gas. There will be stops for potty breaks a snack and stretch and through-town traffic to eat up some of your gas, plus don't take chances cutting things close. Just the trip will take you 22.2 gallons- one tank down and one tank back and the procession to the reception.

Maybe a calculator might help? LMAO
