b: cost of the battery

The cost of both items in £ is given by:

Therefore, we have the following equation:

Then, we know that:

The torch costs eleven times as much as the battery.

Substituting equation two in the equation we have:

Clearing the value of b we have:

The cost of the battery is 0.43 £
