Answer:
The cost of gas is £67.81
Step-by-step 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: [tex]8631-8247=384[/tex]
The cost of the gas is 11p for each unit.
Therefore, the cost is: [tex]384\times 0.11=42.24[/tex]
Also there is a fixed charge of £25.57.
Hence, the cost of gas is [tex]42.24+25.57=67.81[/tex]
