So...

x=initial

x*1.12=26.88

Therefore x=26.88

                     ........

                    1.12

Answer:£24.00

You are right, 12% is indeed 0.12.

However for the percentage increase you add this to 1 to make 1.12

So you add 1+ to make it 1.12 when dealing with these types of percentage problems
