How do I estimate demand using MULTIPE REGRESSION in Microsoft Excel?

I've already added the analysis tools. I've done a Regression for two variables (one independent and one dependent). My textbook is worthless. I have to come up with the equation to the Demand curve for soda using multiple regression analysis. My data set has 5 columns. The first is a list of the 48 contiguous states, the second is the DEPENDENT VARIABLE (sales data for each state), the next three are the INDEPENDENT VARIABLES (various other data: Mean Income, Mean Price, Mean Temperature.). There are other parts to the problem that I'm not worried about like interpreting the coefficients, and simple regression. I NEED TO KNOW HOW TO DO THE MULTIPLE REGRESSION AND THEN PUT THE DATA INTO AN EQUATION. I'm offering $10 to the person that can lead me to the correct answer for this part. I will Paypal $20 to that person if I get the rest of the problem correct. Email me for a copy of the data set if you need it: matt_66002@yahoo.com .

Is anyone worried about the asteroid that could hit earth?

An asteroid that could cause much destruction on earth will come close to earth on July 3rd, 2006.
http://neo.jpl.nasa.gov/cgi-bin/db_shm?des=2004%20XP14

July 3, 2006. Asteroid 2004 XP14 passes near earth, very close, only 1.1 lunar distances (so about the distance of the moon). With a 400-900 meter estimated diameter, it would be very bad news if it hit earth (giant tidal waves, huge explosion).
