I’m working on a writing report and need an explanation and answer to help me learn.

Create an inventory list for one engine or ladder apparatus from your department. Excel or table formats are fine. No text or APA formatting is necessary. Research the cost or value of each item on list and total the cost of all equipment carried. If you do not have access to an apparatus, use the ISO equipment list that is posted under course documents.You must identify the apparatus that your inventory list comes from by dept. name, unit number, year of manufacture, and make.List should be as complete as possible and include all significant equipment. Do not inventory small items such as contents of tool boxes or first aid kits. You are required to identify your sources for pricing information.
