Don't you maintain an internal database to track expenses and inventory? If not, you really should consider doing so.

This is a sizing exercise where your assumptions, common sense and judgment are weighted with your thought process. You have to prove that you are not afraid to make sound assumptions based on comparable information or common size calculations and reach a final result (regardless of actually accurate) through a logical step by step process.

As many as people come to the building. Everyone needs light to light up their path and work
