The cost is still $50, and the cost to prepare it for sale is $20, so the net realizable value is $45 ($115 market value - $50 cost - $20 completion cost). Since the net realizable value of $45 is lower than the cost of $50, you should record a loss of $5 on the inventory item, thereby reducing its recorded cost to $45.
Scenes in Art. The Nile River often influenced the content of Egyptian art. A boat with many oars was a common scene in Predynastic art, but scenes involving hunting or vegetation along the Nile were depicted in art across many periods.
The earliest Egyptian art is very different from that of the pyramids and temples of the Pharaonic period. As early as the eighth millennium BC, the first inhabitants of the Nile Valley began to make engraved drawings on the cliffs, particularly in Upper Egypt and Nubia.
