Answer:
Let's call the normal price of the jacket "x".
We know that the price was reduced by 15%, so we can set up an equation:
x - 0.15x = x(1-0.15) = 0.85x
We also know that the price was reduced by £19.50, so we can set up another equation:
x - 19.50 = 0.85x
Now we can solve for x:
0.15x = 19.50
x = 130
Therefore, the normal price of the jacket is £130.
