Any Mathematicians Out There
I'm sure the answer is simple but my old brain has stopped working. My petrol tank was 25% full. I topped it up to full and it cost me £40. If I had let the tank run empty how much would it cost to fill it up to 100%? I would be grateful if you could explain how you worked it out. thanks in advance

Three quarters of a tank cost you £40. So one quarter of a tank would have cost you a third of that = £13.33. Add that onto the three quarters, to give you a full tank, and you get £53.33.

75% of your tank cost you £40. If you divide 40 by 75, you get the value of 1%. That is 0.53. If you multiply the value of 1% by 100 you get £53.33. That is what it would cost you, roughly to fill up your take from empty.
Although in reality it would cost a lot more. a) because petrol tanks normally have a small reserve and b) if you run out of petrol, you are then going to have the additional cost of getting your car to a fuel supply or a fuel supply to your car.

Depends what the fuel price had risen to since you last filled up!
Assuming the fuel price of the two fills was exactly the same:
(40/3)*4 = £53.33
Assuming the fuel price had risen 20% since your last fill-up:
(40/3)*4*1.2 = £64.00

>>> Buenchico, it costs about £45 to fill up my Mini
Nearly all minis have a 40 litre petrol tank. At 163.28p per litre (which is the current UK average price, according to the RAC website). That's about £65 for a full tank when refilling from empty.
The 'average family car', that's so often cited by the media, has a 55 litre tank. That costs about £90 to fill from empty.
