Final answer:
To reduce the loss on kebabs to 10%, the shop should charge approximately £6.10 per kebab.
Step-by-step explanation:
To find the new price the shop should charge per kebab in order to reduce its loss on kebabs to 10%, we can use the formula:
New Price = Original Price / (1 - Loss Percentage)
Given that the current price is £4.88 and the current loss is 20%, we can calculate:
New Price = £4.88 / (1 - 0.20) = £4.88 / 0.80 ≈ £6.10
Therefore, the shop should charge approximately £6.10 per kebab to reduce its loss to 10%.
