Amina posts three large letters the postage is the same for each letter she pays with a £20 note her change is £14.96 what is the cost of posting one letter?

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
