Let the original price = x

An increase of 10 % = 18.15

Multiply x by (1 + percent increase) which is 1.1x = 18.15

Now to find x divide both sides by 1.1:

X = 16.50

The original price was 16.50

Answer:

£16.50

Step-by-step explanation:

Let cost price be x

Now, create a formula:

x + 10x / 100 = 18.15

'or'

110x / 100 = 18.15

'or'

x = (18.15*100) / 110

x = 16.5
