The manager would like to start creating a "Guest ID" that can be used by the cleaning staff. In cell B4, create a guest ID with the pattern: Guest Last Name Room: Room # of Guests. For example, if there are two guests with the last name of West staying in the Coolidge room the guest id would be "West Room: Coolidge 2" without the quotation marks. Use the CONCAT (or CONCATENATE) function. Reference the Guests Last Name, Room and # of Guests in your function. Pay close attention to the spaces in the Guest ID. Copy and paste the function down the column to create the "Guest ID" for the other transactions
