Answer:
The cost of posting one letter = £1.68
Step-by-step explanation:
Total amount Amina has = £20
Amina's change = £14.96
Total cost spent on posting the letters = £20 - £14.96 = £5.04
And we're told that she posts 3 letters in total, with the cost of posting each letter the same.
Cost of posting 3 letters = £5.04
Cost of posting only 1 letter = (£5.04/3) = £1.68
Hence, the cost of posting a letter = £1.68
