Answer 1

The cost of gas is £67.81

Explanation:

Consider the provided information.

The gas meter readings at the beginning and end of a period were: 8247 and 8631.

The unit used is:
`8631-8247=384`

The cost of the gas is 11p for each unit.

Therefore, the cost is:
`384* 0.11=42.24`

Also there is a fixed charge of £25.57.

Hence, the cost of gas is
`42.24+25.57=67.81`
