its all going to depend on your miles per gallon, assuming you get around 30 the formula to find it out would be:
700 (miles) divided by 30 (your mpg) = 23.33333 (about 23.5 gallons)
23.5 times cost of gas (lets say 2.50)
23.5 * 2.50 = $58.75

700 mi / 22 MPG = 31.81 gal * $2.8/gal = $90
700 miles at 8 mpg means you will use around 87.5 gallons of fuel. At $3.85 per gallon it will cost you around $336.
$121.74
$155.56
700 miles at 45 mpg = 15.55... gallons = 70.72 litres (approx) @ 1.42 per litre, it will cost 70.72*1.42 = 100.42 units of currency.
You will burn about 54 gallons of gas on the trip. This will cost you about $162.00

It all depends on the miles per gallon that a given vehicle gets. 700 / mpg * 4 = cost
If you average 22 miles per gallon on the 700 mile journey, it will take 700/22 gallons to complete. 700 miles / 22mpg = 31.818 gallons.
