Answer:
She paid tax of £18240
Explanation:
We are told that Carys earned £45600 before tax.
Now, from the question, the tax rate that applies is 40%. This is because she earned £45600 and we are told that earnings in excess of £43000 and up to £150000 taxed at a rate of 40%.
Thus;
Tax payable = 40% × 45600
Tax payable = £18240
