In-Game Economy Assignment

What I am needing is a working economy within my story for a game.  There are a total of ten questions that need to be answered pertaining to the economy in the story to keep it balanced.  An Excel spreadsheet needs to be included showing the inventory system and an explanation of the inventory and how it relates to the economy.  An example of everything needed is attached, as well.  I will provide the story, once an agreement is made.  Thank you.

PS.  The answer given should look similar to the examples provide below.
