first try to identify how much gas units you've actually used. then if it's 11p per unit you should be able to carry out a basic calculation to find the cost.

however there's also a fixed charge which must be included so add that on the end as well

8631-8247 = 384 units of gas used

11p * 384 units = 4224p or £42.24

£42.24 + £25.57 = £67.81 as final answer.

That wasn't too hard now, was it? I created an account just for this lol
