You own your own small party supply and rental business. You maintain an Excel list of potential customers and clients who have rented or purchased from you in the past two years. The list includes both physical mailing addresses and e-mail addresses for each person listed. You have a "category" code to show whether the contact is a client. If they have done business with you, they show a code of "CUST" for customer. If they are potential customers who have not yet purchased or rented from you, they are coded as "PROS" for prospect.

You want to grow your business, and feel the best way to do this is to solicit business from your prospects who have physical addresses in the same zip code as your business location. Respond fully to the following questions regarding this task:

A - Explain how you will use Excel to find in your list the people you are targeting for new business. Be specific.
B - You have used your computer skills to develop and print a beautiful flyer, and you intend to mail it to your prospects. However, you dread hand addressing the envelopes. Explain how you might use Excel to make this go faster.
C -  If you get the results you expect to get from contacting your prospects, you want to be able to do this every month. Explain how you might use Excel to automate the process of separating your list as you did in Part A.
D -  Your list is extensive, and mailing letters is expensive. Cost is $15 for every 50 letters mailed. You want to gauge the impact on your income statement of mailing 50, 100, 200, and 400 letters. Explain how you might evaluate this using your Excel tools.
