I have included a screenshot of an example problem I am taking about. When trying to determine the economic order quantity, I seem to be having some troubles. This type of question is advanced for the class I am in. Can you please help me understand how to solve each part in an equation/logarithmic form? I AM NOT USING YOUR WORK AS MY OWN. I just included the problem so that you would be provided with numerical values in your explanation.

Economic order quantity. Exact Copies Incorporated currently orders paper every month for its operations and stores them at a central warehouse. Annually, the company uses 12,800,000 reams of paper. Each order costs $465 for delivery to the warehouse. Exact also estimates that the average cost per year to store a ream of paper is $0.04. Using a spreadsheet, determine the total annual inventory cost of ordering every week, every other week, monthly, every other month and quarterly. Find the economic order quantity (EOQ) for Exact Copies. How often should it order? Finally, visually prove the E00 by calculating the total order cost for order sizes at 25,000 increments (up and down) over a range of 500,000 (EOQ - 250,000 to E00 + 250,000) with the E00 as the midpoint by graphing total inventory costs, total annual ordering costs, and total annual carrying costs. Using a spreadsheet, determine the total annual inventory cost of ordering every week, every other week, monthly, every other month and quarterly. Calculate the total annual inventory cost below: (Round up the quantity ordered to the nearest whole number and the dollar mounts to the nearest dollar.)
