Given clue error:
A return of $67 of defective supplies was erroneously posted as a $76 credit to supplies.

What will I do? Please. Help me, I need the answers now. Thanks in advance. :) Hoping for your consideration.

First you should cancel out the $76 Credit by Debiting Supplies for $76

Next you should Credit Supplies for $67
