Cost of gas would be :
1) No of units used by the consumer - subtract the numbers at the beginning and at the end of the month. (example - 100 units and 450 units. So, units consumed in a metre cycle or one month are 350).
2) 1 unit is 11p. So for 350 units, it would be - 350 X 0.11 = 38.50
3) As there is a fixed price of 25.57
4) Add that to 38.50
5) Total cost of Gas = 38.50+25.57 = 64.07
