What is the conditional formatting rule to highlight the package dates that are 30 days or older than the manufacture date in B4?

Dairy Farm You are the product manager for Schaefer Dairy farm, a local organic farm that produces dairy products. Each month you must run an inventory report to identify and discard expired products before they are sold. Open e04b2Dairy and save it as e04b2Dairy LastFirst. Convert the range A5:E105 to a table, give the table a name, and apply a table style. DISASTER RECOVERY Freeze all data above row 6 and create a conditional formatting rule that highlights any package date that is 30 days or older than the manufacture date in B4. Sort the table first by the newly created highlight color then by department. Next, in column E create an IF function using structured referencing to determine the course of action for expired products. The function should display discard if the product is expired and nothing if the product is still sellable. Filter the table to display only items that should be discarded then add a total row that counts the number of items to discard, Format the table so the column headings print at the top of each page and create a footer with your name, the sheet name code, and the file name code. Save and close the file. Based on your instruc- tor's directions, submit e04b2Dairy_LastFirst
