Your company is planning a party for employees, and you have been asked to set up a spreadsheet to track the attendees and to measure the associated cost. Every employee is permitted to bring one guest to the party. There are 50 employees in your company. The spreadsheet requires to be set up when the invitations are distributed so that you can begin recording the reservations as soon as they come in.
 
The costs of the party are the similar for each attendee. When the employees respond, you want to add their names to the list. If they are not coming, you want this recorded. If they are coming alone, the cost is $45. If they are bringing a guest, the cost is $45 X 2. Respond fully to the following questions regarding this task:
 
A - Describe how you will structure your worksheet, including the titles, column headings, the formulas to measure the cost for every employee (which may include cost for a guest), and to measure the total cost of the party.

B - The facility where the party is to be held will give the company a reduction in price if more than 75 people attend. The price per person will then be $40. Describe how you will set up your worksheet to reflect a change when the total number of attendees hits 75. 
C - You want the employees who are going to attend to show up on the list with a yellow background. Explain the method you would use to have this automatically occur when you indicate the employee's response.

D -  You know your management team will want to periodically check to see who is attending. They are not concerned with those who have responded but are not attending. Explain how you might generate this list as requested using your knowledge of Excel.
